**540 (Spartan) Super7 2D/3D Ultra-AGP Single C.S.<11/30/99
***Info:
The single chipset, SiS540, provides a high performance/low cost
Desktop solution for the Super Socket 7 series CPUs based system by
integrating a high performance North Bridge, advanced hardware 2D/3D
GUI engine and Super-South bridge. In addition, SiS540 provides
system-on-chip solution that complies with Easy PC Initiative which
supports Instantly Available/OnNow PC technology, USB, Legacy Removal
and Slotless Design and FlexATX form factor.
By integrating the Ultra-AGP technology and advanced 128-bit graphic
display interface, SiS540 delivers high performance and up to 2 GB/s
memory bandwidth. Furthermore, SiS540 provides powerful slice layer
decoding DVD accelerator to improve the DVD playback performance. In
addition to providing the standard interface for CRT monitors, SiS540
also provides the Digital Flat Panel Port (DFP) for a standard
interface between a personal computer and a digital flat panel
monitor. To extend functionality and flexibility, SiS also provides
the "Video Bridge" (SiS301) to support the NTSC/PAL Video Output,
Digital LCD Monitor and Secondary CRT Monitor, which reduces the
external Panel Link transmitter and TV-Out encoder for cost effected
solution. SiS540 also adopts Share System Memory Architecture which
can flexibly utilize the frame buffer size up to 64MB.
The "Super-South Bridge" in SiS540 integrates all peripheral con-
trollers/accelerators/interfaces. SiS540 provides a total commun-
ication solution including 10/100Mb Fast Ethernet for Office
requirement. SiS540 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. SiS540 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 controller with four USB ports that deliver better
connectivity and 2 x 12Mb bandwidth.
The built-in fast PCI IDE controller supports the ATA PIO/DMA, and the
Ultra DMA33/66 function that supports the data transfer rate up to 66
MB/s. It provides a separate data path for two IDE channels that can
eminently improve the performance under the multi-tasking environment.
