| Research Abstract |
Effectiveness of multi-core processors for electro-holography was showed. A multi-core processor has plural calculation circuits. Electro-holography requires enormous information processing. The multi-core processors I used were GPU, Cell, ClearSpeed accelerator and GRAPE-DR chip. In the calculation with single precision, GPU was the best. GeForce GTX 280 (GPU) recorded the speed of beyond 100 times than Intel Core 2 Duo (CPU). In the calculation with double precision, GRAPE-DR showed good result. It was 7 times faster than Intel Core i7 (CPU).
