VIA C7 硬件 SHA-256 公布的性能数字并不惊人。只有 1500 khash/s 左右。想想看，硬件实现并不意味着快得离谱。它仍然要走完所有步骤。只有把硬件简化到单一用途、小到能并行塞下很多个，才会快。这不一定容易，也不一定理所当然。

英文原文

The performance numbers posted from a VIA C7's hardware SHA-256 weren't astronomical. Only in the 1500 khash/s range. If you think about it, just because it's implemented in hardware doesn't mean it's crazy fast. It still has to do all the steps. It's only if simplifying it down to single-purpose hardware makes it small enough to fit many in parallel. That's not necessarily easy or a given.
