Aliasing conflict!

This is about doing histogramming on an FPGA, not a tool to group FPGA dice into speed grades :)

Would be interesting to see how an FPGA stacks up against a GPU on this problem. GPUs are very fast at parallel histogramming, but hardwiring the number-to-bin-index computation for a particular problem instance might buy you quite a bit of energy efficiency, or even possibly a bit of performance if the computation involves a divide. If the bins are of non-uniform size and the indexing computation involves a binary search on a lookup table, it seems like the much higher clock speeds on a GPU would win out.
