Speeding up code with GCC's prefetch extension-> 0

birge writes "In memory-constrained loops where memory must be accessed out-of-order, a relatively little-used extension to GCC can be used to speed up code by as much as several times. Extremely simple to use, the __builtin_prefetch instruction tells the cache mechanism to load a memory location into local chip cache, allowing the programmer to have memory loaded for the next computation in parallel with the current computation."
