The single chipset, SiS730S, provides a high performance/low cost Desktop solution for the AMD Athlon™ SlotA/SocketA series CPU based system by integrating a high performance North Bridge, an advanced hardware 2D/3D GUI engine, Super-South bridge and an AGP 4X Slot. In addition, SiS730S 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 2D/3D graphic engine, SiS730S delivers AGP 4X performance and memory bandwidth of up to 1GB/s. In addition, SiS also supports an extra AGP Slot that supports AGP 4X capability and Fast Write Transactions. Furthermore, SiS730S provides a powerful hardware decoding DVD accelerator to improve the DVD playback performance. In addition to providing the standard interface for CRT monitors, SiS730S 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.
The "Super-South Bridge" in SiS730S integrates all peripheral controllers / accelerators / interfaces. SiS730S provides a total communication solution including 10/100Mb Fast Ethernet for Office requirement or HomePNA for Home Networking. SiS730S 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. SiS730S also provides an 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 bandwidth.
The built-in fast PCI IDE controller supports the ATA PIO/DMA, and the Ultra DMA33/66/100 functions that deliver the data transfer rate up to 100 MB/s. It provides the separate data path for two IDE channels that can eminently improve the performance under the multi-tasking environment.
