-based transfers, and low-voltage signaling to provide an extremely powerful, scalable bus for an x86 processor.
The AMD Athlon XP processor model 8 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) operations based on the MMX instruction model, the AMD Athlon XP processor model 8 can
produce as many as four, 32-bit, single-precision floating-point results per clock cycle. The 3DNow! Professional
technology implemented in the AMD Athlon XP processor model 8 includes new 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 new instructions for Digital Signal Processing (DSP) and communications applications.
