• Highly Integrated RAMDAC™ and Triple Clock
Synthesizer
• Full Feature High Performance 3D Graphics Engine

2.7 High Performance 64-bit 2D GUI
The 64-bit graphics engine of the Video-107PCI -3D
significantly improves graphics performance through
specialized hardware that accelerates the most frequently
used GUI operations and matches the high-speed
requirements of CPUs. Functions directly supported in
hardware include: BitBLTs, image and text transfer, line draw,
short stroke vector draw, rectangle fills, and clipping.
The graphics engine supports 256 Raster Operations
(ROPs) for up to 32-bit packed pixel graphic modes. The
ROP3 Processor in the Video-107PCI -3D is able to perform
Boolean functions which allow many additional operations,
including transparency, pattern masking, color expansion
alignment, and pattern enhancement. Additionally, the
graphics engine features linear display memory addressing,
accelerated color expansion modes for graphics text
procession, and memory-mapped I/O registers on the
graphics engine for faster access time.
A 64-bit internal data bus and a four-color hardware
cursor/pop-up icon, operating up to a 128x1128x2 pixel
9
image, which off-loads the CPU, optimize graphic functions.
The hardware cursor mechanism can also be used to display
patterns stored in the system memory. This pop-up icon is
very useful to display user-friendly information instantly
through simple hot key operations.
This advanced function combination allows significant
performance increases over standard Super VGA designs
and provides outstanding graphics acceleration on GUIs,
such as Microsoft ® Windows 95.
2.8 Highly Integrated RAMDAC
The highly integrated design of the Video-107PCI -3D offers a
“no TTL” solution for cost-effective, high-performance
multimedia subsystem designs for the IBM ® PC and
compatible notebooks. The 64-bit memory data bus
supporting SDRAM and SGRAM memory provides faster data
transfer rates for improved system throughput. The Video107PCI -3D has a built-in, high speed RAMDAC™. The
RAMDAC™ is composed of one 256x24 and one 256x18
color lookup table and a triple loop frequency synthesizer,
providing the read/write timing control for the Frame Buffer
Memory and the refresh of the TV/CRT display.
Video processor features include: on-chip hardware Color
Space Conversion (CSC) for faster data conversion on the fly,
Horizontal/Vertical (H/V) scaling with interpolation, edge
recovery algorithm, gamma correction, and overlay control
with different color depths from graphics. The Video-107PCI 3D also includes a fully integrated GUI accelerator, read
cache, and command FIFO that optimize memory bandwidth
and maximize graphics performance.

2.9 Full Feature High Performance 3D Engine
The Video-107PCI -3D is equipped with an advanced
Graphics Drawing, Single Cycle 3D Graphics Engine that
performs premium 3D functions at a high level of more than
1M triangles per second. The 3D engine supports Microsoft ®
Direct3D. The 3D Engine is set up to off-load the CPU from
major 3D tasks including slope calculation, sub-pixel
positioning, and Tri-striping. By balancing 3D pipeline and
reducing parameter passing, the Video-107PCI -3D
approaches the high levels of performance. The 3D engine is
integrated with a triangle set-up engine that sets up triangles
according to the input data of triangle vertex and
10
accomplishes various functions for 3D rendering. Gouraud
shading provides smooth shading for colors across
surfaces, perspective correction texture mapping to correct
texture data based on the perspective, bi-linear texture
filtering for interpolating, alpha blending to compensate
colors for the opacity of two colors blended, Z-buffering (16bit/24-bit), video texturing to overlay 2D video play-back onto
3D images, fogging to simulate weather effects, palletized
texture mapping 8-bit for memory and bandwidth reduction,
and anti-aliasing to reduce or eliminate jaggies resulted from
alias rendering. The 3D engine also works with the APM
system, conserving power while the 3D operations are
suspended.
2.10 TrueVideo® Processor
The Video-107PCI-3D, with an integrated Video Display
Engine, supports apertures on the PCI bus which enables
independent graphic and video data to be transported
simultaneously to and from different memory areas and
greatly accelerates the performance of both DirectDraw™ and
DirectVideo™. The video image is stored in the off-screen
memory and is retrieved by the Video Display Processing
block for TrueVideo® processing.
With the help of DirectDraw™ acceleration for sprites, page
flipping, double buffering, and color keying, TrueVideo®
processing is performed by utilizing Trident’s proprietary
edge recovery algorithm for sharper line visibility, deinterlacing, anti-tearing, multitap horizontal filtering, dithering,
and scaling operations with bilinear interpolation in both
horizontal and vertical directions. The linear scaling permits
zoom in/out to any size without any restrictions. In addition,
the on-chip hardware Color Space Conversion (CSC)
accelerates conversion for 16 bit YUV pixels into linear true
color 32 bit RGB pixels on the fly. The additional X and Y
minifiers are capable of shrinking the video images to any
linear fractions, which saves bus bandwidths and memory
space. The YUV planar of the Video-107PCI -3D supports a
YUV 420 format that can remove redundant video stream
decoding procedures. The color and luminance control
provided by the Video-107PCI -3D offers color
compensations to prevent color distortion for display devices.
