The SiS761GL, a HyperTransport™ to MuTIOL® Bridge with a Mirage™ 1 graphic engine, integrates a high performance HyperTransport™ interface for the AMD Athlon™ 64 processor and Sempron™ processor family, a Mirage™ 1 graphic engine, and SiS MuTIOL® Technology, which connects with the SiS965L MuTIOL® Media I/O. The HyperTransport™ interface of the SiS761GL features HyperTransport™ compliant bus driver technology to support AMD Athlon™ 64 / Sempron™ processors up to 1600MT/s data rate.
The integrated Mirage™ 1 graphic engine features a 3D, a 2D Graphics engine, a video accelerator, and a MPEG I/II motion compensation decoder. To maintain a cost-effective PC system, SiS761GL adopts the UMA, and eliminates the need and thus the cost of the frame buffer memory by organizing the frame buffer in the system memory from programming the system BIOS.
The integrated Mirage™ 1 graphic engine integrates a high performance / high quality 2-pixel pipelined 3D graphics engine comprising a programmable 512KB to 4MB Command Queue sustaining zero-wait 3D-command acceptance, a 32 bit floating point Setup Engine specially designed to fit the entire Microsoft Direct3D API data formats and a built-in Texture Cache significantly improving texture mapping performance. It also integrates a 128 bit 2D accelerator with a 1T pipeline BITBLT engine.
SiS MuTIOL® technology is developed into three layers: the Multi-Threaded I/O Link Layer delivering 1.2GB/s bandwidth to connect embedded DMA Master devices and external PCI masters to interface with the Multi-Threaded I/O Link Layer, the Multi-Threaded I/O Link Encoder / Decoder in SiS965L to transfer data at 1GB/s bandwidth from / to the Multi-Threaded I/O Link Layer to / from the SiS761GL, and the Multi-Threaded I/O Link Encoder / Decoder in the SiS761GL to transfer data at 1GB/s from / to memory sub-system to / from the Multi-Threaded I/O Link Encoder / Decoder in SiS965L.
