Preliminary Information AMD-K6™-2E+ Embedded Processor Data Sheet 23542A/0-September 2000 1.3 Super7™ Platform The Super7 platform is an extension to the popular Socket 7 platform. AMD and its industry partners have invested in the future of Socket 7 with the Super7 platform initiative. The goal of the initiative is to maintain the competitive vitality of the Socket 7 infrastructure through a series of enhancements, including the development of an industry-standard 100-MHz processor bus protocol. In addition to the 100-MHz processor bus protocol, the Super7 initiative includes the introduction of chipsets that support the AGP specification, and support for a backside L2 cache. Currently, over 40 motherboard vendors and all major BIOS and chipset vendors offer Super7-based products. All AMD-K6 embedded processors in CPGA packages remain pin compatible with existing Socket 7 solutions; however, for maximum system performance, the AMD-K6-2E+processor works optimally in Super7 designs that incorporate advanced features such as support for the 100-MHz frontside bus and AGP graphics. 100-MHz Processor Bus The AMD-K6-2E+ processor supports a 100-MHz, 800 Mbyte/second frontside bus to provide a high-speed interface to Super7 platform-based chipsets. The 100-MHz interface speeds up access to main memory by 50 percent over the 66-MHz Socket 7 interface - resulting in a significant 10 percent increase in overall system performance. Accelerated Graphics Port Support Accelerated Graphics Port (AGP) support improves the performance of video graphics systems that have small amounts of video memory on the graphics card. The industry-standard AGP specification enables a 133-MHz graphics interface and will scale to even higher levels of performance. Support For Backside L2 Cache The Super7 platform has the 'headroom' to support higher-performance AMD-K6 processors like the AMD-K6-2E+ processor, which features a full-speed, internal backside 128-Kbyte L2 cache designed to enable new levels of performance to leading-edge embedded systems. 8 AMD-K6™-2E+ Embedded Processor Chapter 1
