I haven't given it serious thought, but would the following idea work?

In Knuth Vol 2, I think Knuth states there is a hardware multiply algorithm that operates in linear time. If it is pipeline-able, then would it be possible to use the standard recursive turn-one-big-multiply-into-3-half-size-multiplies until you got down to say 10,000 bit chunks, then feed these 10,000 bit chunks to the pipelined FPGA multiply algorithm.
