The following table summarizes the latencies of MMX/iSSE instructions on the Intel Pentium III and Pentium 4 processors, and on the AMD Athlon processor: Instruction Pentium III Pentium 4 AMD Athlon MOVD mm,r32 1 2 3 MOVD r32,mm…
The following table lists the Instruction Sets supported by each processor. Processor MMX Extended MMX SSE SSE2 3DNow! Intel Pentium Intel Pentium MMX Intel Pentium II …
The Intel P6 core, introduced with the Pentium Pro processor and used in all current Intel processors, features a RISC-like microarchitecture and an out-of-order execution unit, representing a radical shift from previous designs. The P6’s new dynamic execution micro-architecture removes…
The MMX instructions are supported by every x86 processor introduced in the market after the venerable Intel Pentium MMX, so it should be fairly safe to assume that the processor that your code is running on has MMX instructions. But…
The Streaming SIMD Extensions enhance the Intel x86 architecture in four ways: 8 new 128-bit SIMD floating-point registers that can be directly addressed; 50 new instructions that work on packed floating-point data; 8 new instructions designed to control cacheability of…
