AMD Sempron™ Processor Model 10 with 256K L2 Cache Data Sheet

31994A—1 August 2004

The AMD Sempron processor model 10 with 256K of L2 cache is binary-compatible with existing x86 software and backwards compatible with applications optimized for MMX™, SSE, and 3DNow!™ technology. Using a data format and single-instruction multiple-data (SIMD) operation based on the MMX instruction model, the AMD Sempron processor model 10 can produce as many as four, 32-bit, single-precision floating-point results per clock cycle. The 3DNow! Professional technology implemented in the AMD Sempron processor model 10 with 256K of L2 cache includes integer multimedia instructions and software-directed data movement instructions for optimizing such applications as digital content creation and streaming video for the internet, as well as instructions for digital signal processing (DSP) and communications applications.

The AMD Sempron processor model 10 with 256K of L2 cache features a seventh-generation microarchitecture with an integrated, exclusive L2 cache, which supports the growing processor and system bandwidth requirements of emerging software, graphics, I/O, and memory technologies. The high-speed execution core of the AMD Sempron processor model 10 includes multiple x86 instruction decoders, a dual-ported 128-Kbyte split level-one (L1) cache, an exclusive 256-Kbyte L2 cache, three independent integer pipelines, three address calculation pipelines, and a superscalar, pipelined, out-of-order, three-way floating-point engine. The floating-point engine is capable of delivering top-of-the-class performance on numerically complex applications.

The AMD Sempron processor model 10 with 256K of L2 cache also includes QuantiSpeed™ architecture, a 333-MHz,

2.7-Gigabyte per second AMD Athlon™ system bus, and 3DNow! Professional technology. The AMD Athlon system bus combines the latest technological advances, such as point-to-point topology, source-synchronous packet-based transfers, and low-voltage signaling to provide an extremely powerful, scalable bus for an x86 processor.
