The SiS755FX, a HyperTransport™ to AGP / MuTIOL® Bridge, integrates a high performance HyperTransport™ interface for AMD Athlon™ 64 FX processor family, an AGP interface, and SiS MuTIOL® Technology, which connects with SiS964 MuTIOL® Media I/O.

The HyperTransport™ interface of SiS755FX features the HyperTransport™ complaint bus driver technology to support AMD Athlon™ 64 FX processors up to 2000MT/s data rate.

The AGP interface of SiS755FX 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 SiS755FX and SiS964 MuTIOL® Media I/O together.

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 to Multi-Threaded I/O Link Layer, the Multi-Threaded I/O Link Encoder/Decoder in SiS964 to transfer data with 1GB/s bandwidth from/to Multi-Threaded I/O Link Layer to/from SiS755FX, and the Multi-Threaded I/O Link Encoder/Decoder in SiS755FX to transfer data with 1GB/s from/to memory sub-system to/from the Multi-Threaded I/O Link Encoder/Decoder in SiS964.
