The SiSM760, a HyperTransport™ to AGP / MuTIOL® Bridge with a Mirage™ 2 graphic engine, integrates a high performance HyperTransport™ interface for the Mobile AMD Athlon™ 64 processor family, an AGP interface, an Mirage™2 graphic engine, a local frame buffer interface and SiS MuTIOL® Technology, which connects with the SiS963L MuTIOL® Media I/O.
The HyperTransport™ interface of the SiSM760 features HyperTransport™ complaint bus driver technology to support Mobile AMD Athlon™ 64 processors up to 1600MT/s data rate.
The AGP interface of the SiSM760 can support external AGP slots with AGP 4X/8X capability and Fast Write Transactions. SiS MuTIOL®, a high bandwidth and mature technology, is incorporated to connect the SiSM760 and SiS963L MuTIOL® Media I/O together.
The integrated Mirage™ 2 graphic engine features a 256-bit 3D, & a 128 bit 2D Graphics engine, a video accelerator, an MPEGI/II motion compensation decoder, and a video link (combined with AGP port) to support TV-out & digital flat panels. To maintain a cost-effective PC system, the SiSM760 adopts the SMA 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. To enhance system performance, the SiSM760 also supports the local frame buffer solution and can support SDRAM and SGRAM.
The Integrated Mirage™ 2 graphic engine integrates a high performance/high quality 256-bit 3D pipelined 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, a built-in Texture Cache significantly improving texture mapping performance, and a programmable Rendering Engine compliant to Direct3D 8.1 Pixel Shader v1.3. It also integrates a 128-bit 2D accelerator with a 1T pipeline BITBLT engine. Two 12-bit DDR digital video links interfaced to the SiS 301/302 Video Bridge is incorporated to expand the SiSM760 functionality to support secondary displays, in addition to the default primary CRT display.
SiS MuTIOL® technology is developed into three layers: the Multi-Threaded I/O Link Layer delivering 1.2 GB/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 the SiS963L to transfer data at 1GB/s bandwidth from/to the Multi-Threaded I/O Link Layer to/from the SiSM760, and the Multi-Threaded I/O Link Encoder/Decoder in the SiSM760 to transfer data at 1GB/s from/to memory sub-system to/from the Multi-Threaded I/O Link Encoder/Decoder in the SiS963L.
