PowerXCell 8i においては，SPE における DMA 転送の最適化などにより，約 350 倍に高速化された．ホモジニアスマルチコアである Intel Xeon においては，OpenMP による並列化や高速アルゴリズムの導入により，約 38

The recursive ZNCC calculation and the census transform, etc. was implemented for acceleration with guaranteed accuracy. The optimizaion on heterogeneous multi-core (IBM PowerXCell 8i) was sped up by about 350 times by optimizing the DMA transfer in SPE .
