AMD-K6™-2E Embedded Processor Features
The AMD-K6-2E processor with 3DNow!™ technology is a functionally compatible embedded version of the sixth generation, Microsoft® Windows® compatible AMD-K6-2 processor. The AMD-K6-2E embedded processor delivers the same high performance and incorporates the same leading-edge features, including the innovative and efficient RISC86® microarchitecture, a large 64-Kbyte level-one cache (32-Kbyte dual-ported data cache, 32-Kbyte instruction cache with predecode data), and a powerful IEEE 754-compatible and 854-compatible floating-point execution unit.
