SSE2

Author: Gabriel Torres Last Updated: January 6, 2006 Category: CPU Streaming SIMD Extensions 2 SSE2 technology is a SIMD concept implementation introduced with Pentium 4 processor. All processors released after the first Pentium 4 have this technology. SSE2 brings 144 new instructions capable of manipulating several small data chunks at the same time. The difference between SSE and SSE2 is that SSE can handle up to 32-bit floating point numbers, while SSE2 can handle up to 64-bit floating point numbers. To use this technology the processor must be SSE2-enabled and the program must be compiled (i.e. written) to use these new instructions.
