alt Hacker NewsSomething like this? 64-bit hash, 9 bits to address all the bits in a 64-byte cache line, so 7 hash functions addressing the bits in a cache line can be extracted from a 64-bit hash?

yeah. You also don't need complete independence. You can use partially overlapping bits to get semi-independent hashes.
