%X A new memory copy function is developed after researching on the operating characters of Streaming SIMD Extensions (SSE) data transfer instructions and taking facts into account such as prefech,alignment,cache and new 128 bits registers. In the function, assemble language embedded in Visual (C++) 6.0 is employed.An experiment is conducted to analyze the relations between the velocity of every memory copy function and the size of memory to be copied.
