6.1 Introduction
This chapter provides a technical description of the DIGITAL PowerStorm 1000 graphics
subsystem and the individual boards and modules that make up the subsystem.
6.2 Subsystem Description
The DIGITAL PowerStorm 1000 graphics subsystem motherboard system bus is called the
DBus. The DBus supports 64 bits of data and 28 bits of address clocked at 66.67 MHz. A
clock skew of +/- 1 ns is maintained throughout the system. Appropriate clock distribution
along with PLL circuitry is critical to the design of the graphics subsystem. The DBus
utilizes bus repeaters spaced at approximately six inch intervals to minimize the effects of
trace length and loading.
The host connection is made through the Workstation Interface Board in the AlphaStation
system via a 32-bit interconnect cable (Hbus) to the Graphics Interface Module in the
graphics subsystem deskside chassis. The Graphics Interface Module uses discrete off-theshelf components and interfaces to the graphics subsystem motherboard. The Hbus
supports up to 130 million bytes per second throughput between the host and DBus.
6
Technical Description
The DBus interfaces directly to the Graphics Interface Module and the Video Memory
Modules via the Raster Controller (RC) ASICs, and the Standard or High Resolution
Module. The Graphics Interface Module is capable of Hbus slaveship as well as DBus
slave/mastership. As a master, it has the capability to send pixels to/from the Video
Memory Modules via the RC ASICs or interface to various peripherals and memory pools
within the system.
DIGITAL PowerStorm 1000 Graphics Subsystem Owner's Guide 6–1
Page 70
Technical Description
The Vertex Data Manager (VDM) ASIC on the Vertex Module provides the interface
between the Graphics Interface Module FIFOs and the Image Rendering Modules. This
VDM ASIC has responsibility for assembling and formatting information for the rendering
pipeline on the Image Rendering Modules. The VDM ASIC also performs Vertex Bus
control.
The Image Rendering Module contains the Super Slicer Dicer (SSLD) ASIC and two Subpixel Area Manager (SAM) ASICs to provide rasterization for anti-aliasing points, lines,
and triangles whose data is stored in Pix Link Memory (PLM) buffers. The final
red/green/blue (RGB) data is transmitted to the RC ASICs.
The RC ASICs are mounted on the Video Memory Modules, one RC per Video Memory
Module. Their main function is to arbitrate incoming pixels generated by the Image
Rendering Modules and/or arriving from the DBus as they funnel into the frame buffer.
The RC ASICs will also configure the frame buffer resolutions, generate the appropriate
video RAM timing, and support pixel operations such as BLT, window erase, and logical
rasterops.

Technical Description
6.3 Module Descriptions
The following sections contain technical descriptions of the boards and modules that make
up the DIGITAL PowerStorm 1000 graphics subsystem.
6.3.1 Workstation Interface Board (WIB_P1)
The Workstation Interface Board is implemented in the form factor of the host computer
bus. It provides a high-speed memory-mapped connection to the graphics subsystem via
the Hbus. It is through the Workstation Interface Board that the host computer may access
any device in the system that interfaces to the Dbus.
The Workstation Interface Board is a single slot PCI bus board that provides the interface
between the AlphaStation system and the PowerStorm 1000 graphics subsystem.
The Workstation Interface Board interfaces to a common "HBus" cable between the
AlphaStation system and the graphics subsystem. In addition, the Workstation Interface
Board provides DMA capabilities from the host memory to the graphics subsystem. This is
a critical feature for off-loading the host from transfer operations due to the high
bandwidth requirements needed to maintain the rendering performance goals of the
graphics subsystem.
The Workstation Interface Board does not provide console support. Instead, the
AlphaStation system will have VGA support provided by a separate VGA Module. A VGA
cable connects the VGA Module in the AlphaStation system to the graphics subsystem's
(entry and full PowerStorm 1000) Standard Resolution Module. An "enable/disable"
switch is provided to switch between the VGA video source and the graphics subsystem's
video source. The Workstation Interface Board contains a PROM for future support.
6.3.2 Motherboard/Backplane (RMB)
The motherboard provides the interconnect and power distribution between the various
modules that make up the PowerStorm 1000 graphics subsystem. In addition to the
numerous connectors that are required to implement this interconnect, the motherboard
contains active components to distribute clocks, provide Dbus bridges that are required to
maintain acceptable skew within the system, Dbus control logic, and a serial I.D. PROM
for identification.
The motherboard contains nine slots to support the following modules:
• One Graphics Interface Module
• One Vertex Module
• Up to four Image Rendering Modules
• One Video Memory Module per Image Rendering Module pair
• One Standard Resolution Module or High Resolution Module
6–4

Page 73
6.3.3 Graphics Interface Module (GIM)
The Graphics Interface Module contains the circuitry to interface between the workstation
cable and the Dbus, and thereby the rest of the PowerStorm 1000 graphics subsystem. The
Graphics Interface Module is capable of operating as a master on the Dbus. In addition to
its host interface function, the Graphics Interface Module contains various ancillary
peripherals and control logic necessary for the rest of the system. The design allows access
from the HBus at a peak bandwidth of 130 MB/second.
Creating the Graphics Interface Module as a separate module facilitates field upgrades to
new interfacing technologies (such as a Fiber channel) and removes many active
components from the motherboard for enhanced manufacturability and maintainability.
The Graphics Interface Module provides the following "Standard I/O" devices for the
PowerStorm 1000 graphics subsystem:
• Interface to the Workstation Interface Board via the Hbus cable
• Flash ROM
• Timer
• Status Registers
Technical Description
• Control Registers
• LEDs
• Dip Switch
• Interrupt Controller
• Serial Interface for in circuit programmable devices
• PROM support circuitry
• JTAG Controller
• LED Display Driver
All I/O devices are accessible to the workstation processor as well as any processor in the
PowerStorm 1000 graphics subsystem.

Technical Description
6.3.4 Vertex Module (VXM)
The Vertex Module contains the Vertex Data Manager (VDM) ASIC, which is the first
state of the rendering pipeline. It has been implemented as its own module to remove a
high pin count BGA package from the motherboard; thereby enhancing manufacturability
and maintainability while providing the capability to replace the entire rendering pipeline
with a future design if required.
The VDM ASIC receives the stream of Image Rendering Module commands from the
AlphaStation system, assembles the data describing the vertices of points, lines, triangles,
and rectangles, computes the additional information needed for their rasterization, and
passes the results to the Image Rendering Module. Commands destined for ASICs further
along the pipeline also pass through the VDM in sequence and with other work, thus
reducing the need for time consuming flush operations.
In addition to its rendering functions, the VDM provides Vertex Bus control.
6.3.5 Image Rendering Module (IRM)
The Image Rendering Module provides rasterization for anti-aliased points, lines and
polygons, depth cueing, multilevel transparency, stenciling, texture mapping, hidden
surface removal, Z ordering of pixels, window clip testing for occluded windows, and
multiple API support. The PowerStorm 1000 graphics subsystem supports configurations
of either two or four Image Rendering Modules.
The module control section provides setup and configuration services while the module
functionality section provides image generation services. The module is implemented
using three ASICs (one Super Slicer Dicer (SSLD) ASIC and two Sub-pixel Area Manager
(SAM) ASICs).
• The SSLD ASIC computes pixel addresses, calculates RGB values and coverage
information for the resulting pixels, applies texture map and depth cue algorithms as
appropriate, and finally passes the pixel fragments into one of two SAM ASICs. The
SSLD also performs Alpha Test and Alpha Modulate functions (required by OpenGL).
• The SAM ASICs contain the necessary facilities for building complex images within
memory buffers called Pixel Link Memory (PLM) buffers.
• Within each Image Rendering Module, four independent banks of PLM buffers serve
interleaved screen pixel locations. They also contain window specific allocation tables
to speed garbage collection for pixel links no longer needed after a swap-buffers
operation. Each SAM manages two banks of PLM buffers in which it allocates and
maintains pixel link lists based on incoming fragments, and computes composite RGB
results to pass on to the Video Memory Module section. The SAM ASICs are
responsible for Stencil/Z tests and operations and fragment blending.
6–6
DIGITAL PowerStorm 1000 Graphics Subsystem Owner's Guide
Page 75
Technical Description
Each pixel link contains RGB, alpha, stencil, and Z values plus a pointer to the next
link. Links are stored in receding Z order. These lists are the heart of the HiFIVE antialiasing system, eliminating the need for presorting primitives and multi-pass
algorithms by retaining enough information at multiple Z depths. Figure 6-2 illustrates
an Image Rendering Module block diagram.
While the fragment modification calculations for texture mapping are part of the SSLD
ASIC, the actual mipmap storage is in separate memory on the Texture Memory Modules.
All Image Rendering Modules in a PowerStorm 1000 graphics subsystem must have the
same amount of texture memory, either 32 MB or 64 MB.

Technical Description
6.3.6 Video Memory Module (VMM)
One Video Memory Module is required if two Image Rendering Modules are in the
PowerStorm 1000 graphics subsystem, two if there are four Image Rendering Modules.
Each Video Memory Module contains a Raster Controller (RC) ASIC and VRAM screen
buffer memory for resolutions of up to 2048 x 1024 containing:
• Eight bits double-buffered red data
• Eight bits double-buffered green data
• Eight bits double-buffered blue data
• Eight bits window identification information
• Eight bits double-buffered overlay information
The RC ASIC manages the random access port of the VRAM, storing pixels assembled by
the SAM ASICs in the Image Rendering Module. The serial port is forwarded to the
Standard Resolution Module or the High Resolution Module with the Window ID (WID)
clocked out several cycles ahead to allow time for the buffer selection information to
propagate back from the Window Attribute Mixer (WAM) ASIC. A block diagram of the
interface to the Video Memory Module is shown in Figure 6-3. A block diagram of a
single pixel is shown in Figure 6-4.

Technical Description
6.3.6.1 Raster Control (RC) ASIC
One RC ASIC is mounted on each Video Memory Module in the subsystem. The RC ASIC
supports a full DBus slave interface for direct access of the frame buffer on the Video
Memory Module or for any of the master units on the DBus. The RC also supports up to
two Image Rendering Module input interfaces. Each Image Rendering Module interface
requires 11 bits of X, 11 bits of Y, and 24 bits of RGB. The RC to video memory interface
is a bi-directional 32-bit data, 10-bit address and 19 bits of VRAM control. The main
functions of the RC ASIC are video DRAM control, screen resolution mapping, raster
operations, and BLT.
All software registers in the RC ASIC are loadable via the DBus interface or the Image
Rendering Module interface for pipeline synchronization.
6.3.6.2 Frame Buffer
The PowerStorm 1000 graphics subsystem frame buffer is configurable. The frame buffer
consists of one or two Video Memory Modules. When configured with the Standard
Resolution Module, the frame buffers transfer four pixels out of the frame buffer during
each video RAM shift register read cycle. When configured with the High Resolution
Module, the frame buffers transfer eight pixels out of the frame buffer during each video
RAM shift register read cycle. Table 6-1 identifies the relationship between the number of
Video Memory Modules in the frame buffer and the maximum screen resolutions
supported.
The Frame Buffer Memory is implemented using 4 MByte video RAMs.

6.3.6.3 Eight-Bit Overlay Planes
Eight-bit double buffered overlay planes are a standard feature of the PowerStorm 1000
graphics subsystem.
6–10
DIGITAL PowerStorm 1000 Graphics Subsystem Owner's Guide
Page 79
6.3.6.4 Control Planes
The PowerStorm 1000 graphics subsystem has several types of control planes:
• Eight window ID planes
• One Z buffer erase plane
• One window clip plane
• Eight stencil planes
• Double-buffered 8-bit overlay/blink planes
A control plane is a frame buffer plane that allocates one bit per pixel to perform a
function on a per-pixel basis that controls how a pixel value is written into or read from the
frame buffer.
The Window ID planes allow the application to control various attributes on a window by
window basis. Attributes under control of the window ID planes include:
• Double buffer control
• Pixel type (indexed or true color)
Technical Description
• Several blink/overlay options
The Z buffer Erase Plane allows the frame buffer hardware to mark DRAM locations used
for Z buffering as erased, even if they have not been. This allows the corresponding
VRAM locations to be erased at full speed without waiting for the DRAM to be erased.
The Window Clip Plane allows windows to be updated by the server without requiring all
updates to be compared against a list of clip rectangles for all the areas that overlapping
windows intersect. This allows high performance rendering in a window environment.
The Stencil Planes are used for particular cases where round-off or truncation error can
cause Z-fighting for objects intended to have the same Z-value.
The overlay/blink planes provide a mechanism to display 8-bit visuals without affecting
the existing image in the true color planes. These are double-buffered. They can also
produce a minimal true color approximation in 3/3/2 (R/G/B) configuration.

Technical Description
6.3.7 Video Generation
The following sections describe video generation.
6.3.7.1 Window Attribute Mixer (WAM) ASIC
The WAM ASIC is responsible for video timing generation, window attribute processing,
and the controlling of the frame buffer data to the RAMDAC. The WAM ASIC processes
RGB data two pixels at a time, generates control for the double buffer select, decodes the
window identification, and modifies the RGB data destined for the RAMDAC based on
this information. Because each WAM processes RGB, the overlay information can be
folded into the RGB pixel stream, relieving the RAMDAC of this responsibility and
providing more flexibility in the processing of the overlay information.
6.3.7.2 Video Output Modules
Two different types of video output modules are designed to support the PowerStorm 1000
graphics subsystem. One (and only one) of the two is configured in each the PowerStorm
1000 graphics subsystem. Each of the configurations relies on four WAM ASICs as an
integral component. This module provides the video signal generation, synchronization to
a variety of resolutions, aspect ratios, and refresh rates. It generates the video out by
merging the contents of the frame buffer memory on the video memory modules. It
provides hardware support for crosshair and cursor RAM and double buffer select control
logic. The double buffer selection process is performed on the video memory module.
6.3.8 Standard Resolution Module (SRM)
One of the video output modules is the Standard Resolution Module. The Standard
Resolution Module supports (1920 x 1280) at 76hz and resolutions of 640 x 480 up to 1920
x 1280. The Standard Resolution Module is the module used when stereographic images
are required. The Standard Resolution Module can be operated with one or two Video
Memory Modules. The block diagram for the Standard Resolution Module is shown in
Figure 6-5.
The Standard Resolution Module provides a video switching capability between an
external VGA video output and the video output from the IBM RGB561 Palette DAC.
Based on the state of a software programmable configuration bit, video will be either from
the IBM RGB561 source or an external VGA source. The default video source setting for
power-up/reset is the external VGA source.

Software has determined that the values read
from Dbus status registers 0 and/or 1 are
invalid. The parameter values are the contents
of these registers.
The Master RC ASIC has received a bad
command. Parameter values are the contents of
Dbus status registers 0 and 1, and the upper
and lower halves of the bad command.
The Slave RC ASIC has received a bad
command. Parameter values are the contents of
Dbus status registers 0 and 1, and the upper
and lower halves of the bad command.
An unexpected interrupt has been received
from an RC ASIC. Parameter values are the
contents of Dbus status registers 0 and 1, and
the contents of the RC status register.
The Graphics Interface Module has detected a
Packet Controller error. Since the PowerStorm
1000 system does not have a packet controller
this event should never be seen. Parameter
values are the contents of Dbus status registers
0 and 1.
The VDM ASIC has detected a bad VDM
command. Parameter values are the contents of
Dbus status registers 0 and 1.
