SiS748 is the first to provide support for advanced technologies such as a 400MHz front-side bus, DDR400 memory spec, AGP8X graphical interface, and MuTIOL® (Miaoqv) 1G, and it also introduces HyperStreaming architecture technology for the first time. It is currently the only core logic chipset on the market for the AMD platform to offer so many top-end specs at once.
In SiS748, SiS exclusively provides dual support for a 400MHz front-side bus and a DDR400 memory controller, which can greatly increase data processing speed and bandwidth and perfectly demonstrate the excellent effect of synchronized operation between system and memory. With its support for the powerful 400MHz front-side bus technology, SiS748 brings DDR400 performance into full play, providing users with a superior operating platform and bringing out the unmatched power of AMD processors.
The high-performance combination of SiS748 with the SiS963L southbridge chip can fully demonstrate the unique appeal of MuTIOL® 1G technology, providing faster and smoother communication between the northbridge and southbridge chips. With an execution speed of up to 533MHz and a 16-bit bidirectional data bus architecture, it supports a transfer rate of 1GB per second, ensuring the fullest possible use of bandwidth and speed. SiS963L also integrates a USB 2.0/1.1 controller, ATA133/100/66 standard dual IDE channels, 5.1-channel audio, V.90 data transmission, and Ethernet networking, providing users with complete high-speed transfer interfaces.
SiS today officially announced that its future K7 platform SiS748 chipset will be the first to use a system bus technology called HyperStreaming, and the SiS748 chipset based on this new technology will also be displayed at CeBIT 2003.
As an extension of MuTIOL, HyperStreaming includes four main technical features, including:
Single Stream with Low Latency, whose specific effect is to make the response time of a single data stream faster and reduce system latency. When the user accesses the hard disk, if direct memory access (DMA) is used, latency can be reduced by at least 5% compared with other platforms. If ordinary single access is used, latency can be reduced by as much as about 43%.
Multiple Streams with Pipelining and Concurrent Execution. Through an overall parallel architecture, this technology can effectively widen data transfer bandwidth and simultaneously process non-sequential data, improving system performance and allowing peripheral devices to work together more flexibly.
Specific Stream with Prioritized Channel. It can identify music and video files downloaded over the Internet and assign dedicated bandwidth and channels for them, ensuring smooth playback.
Smart Stream Flow Control. Through management by the Smart Arbiter, when dealing with external chipset interfaces, this technology can make serial streams more efficient according to differences in protocol and characteristics, and can even improve the usable access space for the processor through effective flow control, thereby increasing system throughput and execution efficiency.
