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.

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.

A block diagram of the DIGITAL PowerStorm 1000 graphics subsystem is shown in Figure 6-1.

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

DIGITAL PowerStorm 1000 Graphics Subsystem Owner's Guide

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.

Table 6-1 Frame Buffer Configurations

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.
