The SiS760GX, a HyperTransport™ to AGP / MuTIOL® Bridge with a Mirage™ 2 graphic engine, integrates a high performance HyperTransport™ interface for the AMD Athlon™ 64 processor family, an AGP interface, a Mirage™ 2 graphic engine, and SiS MuTIOL® Technology, which connects with the SiS964 MuTIOL® Media I/O.
The HyperTransport™ interface of the SiS760GX features HyperTransport™ complaint bus driver technology to support AMD Athlon™ 64 processors up to 1600MT/s data rate.
The AGP interface of the SiS760GX can support external AGP slot with AGP 4X/8X capability and Fast Write Transactions. SiS MuTIOL®, a high bandwidth and mature technology, is incorporated to connect the SiS760GX and SiS964 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, a MPEG1/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, SiS760GX 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.
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 301/2 Video Bridge is incorporated to expand SiS760GX functionality to support secondary displays, in addition to the default primary CRT display. SiS301 Video Bridge features an NTSC/PAL video encoder with Macro Vision Ver. 7.1.L1 option for TV displays, a TMDS transmitter with Bi-linear scaling capability to support up to UXGA TFT LCD panel, and an analog RGB port to support a secondary CRT. The primary CRT display and the extended secondary display, namely TV, TFT LCD, or 2'nd CRT, feature Dual Display Capability in the sense that both can generate the display in independent resolutions, color depths, and frame rates.
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 SiS964 to transfer data at 1GB/s bandwidth from/to the Multi-Threaded I/O Link Layer to/from the SiS760GX, and the Multi-Threaded I/O Link Encoder/Decoder in the SiS760GX to transfer data at 1GB/s from/to memory sub-system to/from the Multi-Threaded I/O Link Encoder/Decoder in SiS964.
