2.2
3D ACCELERATOR
Targeting on Microsoft Direct3D and OpenGL acceleration, SiS300 achieves extremely high
fill and polygon rate in superior quality with high balanced pipeline 3D architecture. The
major key technologies that guarantee a high 3D performance are the integrated Turbo
Queue, Setup Engine, Texture Cache, and Pipeline Render Engine.
The major technologies for the high performance and high quality 3D rendering in SiS300
are:
Turbo Queue
Setup Engine
Texture Cache
Pipelined Rendering Engine
Turbo Queue in 3D Accelerator
Using the Turbo Queue architecture (
SiS patent) will speedup the rendering for 3D engine.
The Turbo Queue length is up to 512KB, therefore 3D driver can issue commands almost
without waiting. To save the high cost for building a long enough hardware command queue,
SiS300 allocates a portion of the off-screen memory as the command queue buffer. Once
SiS300 detects the status of the internal hardware command queue nearly full, some of the
commands in the hardware queue will be temporally swapped to the off-screen area. When
2D or 3D engine finishes previous command, these off-screen commands will be read back
first as the next command for execution.
In SiS300 architecture, 2D and 3D engines share the same hardware queue and off-screen
command queue but only one engine is active at a time. In this way, we can guarantee a
correct execution sequence.
Setup Engine
Setup Engine is one of the most critical parts in the new generation 3D design. It calculates
and prepares all of the parameters for primitive drawing. All these computations need more
than hundreds of addition, subtraction, multiplication, and division. If we make this setup
calculation by host CPU, the sequential coding and processing form a bottleneck for 3D
rendering.
To off-load this computation time from host CPU and to do it in parallel, SiS300 integrates a
VLIW-like 32-bit floating point Setup Engine. It can finish all of the setup computations for a
triangle within 60 memory clocks. Moreover, Setup Engine also supports line and point setup
calculations with much less memory clocks than triangle setup required. This Setup Engine,
specially designed to fit all the data formats in Microsoft Direct3D API, can accept vertex
