Mastering Assembly Programming

Summary

The example code in this chapter was designed for the demonstration of the parallel data processing capabilities of modern Intel-based processors. Of course, the technology being used herein is far from able to provide the power of architectures such as CUDA, but it is definitely able to significantly speed up certain algorithms. While the algorithm we worked on here is very simple and hardly requires any optimization at all, as it could be implemented with FPU instructions alone and we would hardly notice any difference, it still illustrates the way in which multiple data may be processed simultaneously. A much better application could be solving an n-body problem, as SSE allows simultaneous computation of all vectors in a 3 dimensional ...
