SiS 651( North Bridge Chipset ) -
Integrated VGA Solution for P4 with FSB 533
SiS651 IGUI Host Memory Controller integrates a high performance host
interface for Intel Pentium 4 processor, a high performance 2D/3D Graphic
Engine, a high performance memory controller, an AGP 4X interface, and SiS
MuTIOL? Technology connecting w/ SiS962 MuTIOL? Media IO.
SiS651 Host Interface features the AGTL & AGTL+ compliant bus driver
technology with integrated on-die termination to support Intel Pentium 4
series processors with FSB 533/400MHz. SiS651 provides a 12-level
In-Order-Queue to support maximum outstanding transactions up to 12. It
integrated a high performance 2D/3D Graphic Engine, Video Accelerator and
Advanced Hardware Acceleration MPEGI/MPEGII Video Decoder for the Intel
Pentium 4 series based PC systems. It also integrates a high performance
2.7GB/s DDR333 Memory controller to sustain the bandwidth demand from the
integrated GUI or external AGP master, host processor, as well as the multi
I/O masters. In addition to integrated GUI, SiS651 also can support external
AGP slot with AGP 1X/2X/4X capability and Fast Write Transactions. A high
bandwidth and mature SiS MuTIOL? technology is incorporated to connect
SiS651 and SiS962 MuTIOL? Media I/O together. SiS MuTIOL technology is
developed into three layers, the Multi-threaded I/O Link Layer delivering
1.2GB 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 SiS962 to transfer data w/ 533 MB/s bandwidth
from/to Multi-threaded I/O Link layer to/from SiS651, and the Multi-threaded
I/O Link Encoder/Decoder in SiS651 to transfer data w/ 533 MB/s from/to
Multi-threaded I/O Link layer to/from SiS962.
