SiS630S
The single chipset, SiS630S, provides a high performance/low cost Desktop solution for the Intel Slot
1 and socket 370 series CPU based systems by integrating a high performance North Bridge, ad-
vanced hardware 2D/3D GUI engine, Super-South bridge or an external AGP4X Slot. In addition,
SiS630S provides a system-on-chip solution that complies with the Easy PC Initiative which sup-
ports Instantly Available/OnNow PC technology, USB, Legacy Removal and Slotless Design and
FlexATX form factor.
By integrating the UltraAGP
TM
technology and advanced 64-bit graphic display interface, SiS630S
delivers AGP 4x performance and memory bandwidth of up to 1 GB/s. In addition, SiS also supports
an extra AGP Slot that supports 4X and Fast Write transactions. Furthermore, SiS630S provides
powerful hardware decoding DVD accelerator to improve the DVD playback performance. In addition
to providing the standard interface for CRT monitors, SiS630S also provides the Digital Flat Panel
Port (DFP) for a standard interface between a personal computer and a digital flat panel monitor.
SiS630S adopts Share System Memory Architecture which can flexibly utilize the frame buffer size
up to 64MB.
The “Super-South Bridge” in SiS630S integrates all peripheral controllers/accelerators /interfaces.
SiS630S provides a total communication solution including 10/100Mb Fast Ethernet for Office re-
quirement and 1Mb HomePNA for Home Networking. SiS630S offers AC’97 compliant interface that
comprises digital audio engine with 3D-hardware accelerator, on-chip sample rate converter, and
professional wavetable along with separate modem DMA controller. SiS630S also provides interface
to Low Pin Count (LPC) operating at 33 MHz clock which is the same as PCI clock on the host, and
dual USB host controllers with six USB ports that deliver better connectivity and 2 x 12Mb band-
