Streaming SIMD Extensions 3

SSE3 technology is a SIMD concept implementation introduced with Pentium 4 processor with “Prescott” core. All processors released after this will have this technology.

SSE3 brings 13 new instructions covering floating point to integer conversion, thread synchronization and one specifically for video encoding.

To use this technology the processor must be SSE3-enabled and the program must be compiled (i.e. written) to use these new instructions.
