SiS755FX North Bridge Chipset for HyperTransport  from 

Product Type: Chipset

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

The HyperTransport™ interface of SiS755FX features the HyperTransport™ compliant bus driver technology to support AMD Athlon™ 64FX processors up to 2.0GT/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 IO 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

Product Features:

  • Supports Athlon™ 64FX CPU
  • Supports HyperTransport™ technology with 8/16 links
  • Supports up to 2 Gigatransfers/second HyperTransport bandwidth
  • PCI Express Graphics Interface support
  • Supports maximum PCI-E bandwidth of 4 GB/s in X16 configuration
  • Highthroughput MuTIOL Connect Interface
  • 1 GB/s MuTIOL performance in 133MHz x 4 mode

PCI-Express support

PCI Express is a new standard for I/O interconnect. It has several advantages over legacy PCI. Furthermore, it is PCI compatible in software. SiS756 integrates a X16 Host-to-PCI Express bridge that is compliant with PCI Express SPEC 1.0a. It also has lane reversal capability to provide maximum flexibility.

The SiS MuTIOL™ Technology

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 SiS965/965L to transfer data at 1GB/s bandwidth from/to Multi-Threaded I/O Link Layer to/from SiS756, and the Multi-Threaded I/O Link Encoder/Decoder in SiS756 to transfer data with 1GB/s from/to memory sub-system to/from the Multi-Threaded I/O Link Encoder/Decoder in the SiS965/965L
