I just realised a platform where your karatsuba addmul_2 could help a lot: atom-64. There, addmul_2 currently runs at 20 c/l. The pipeline is two-way superscalar and in-order. The mul insn can be repeated someting like one every 16th cycle.
There is a dual-core atom-64 in the test systems setup, hehe.gmplib.org. It is currently offline for various reasons. -- Torbjörn _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org http://gmplib.org/mailman/listinfo/gmp-devel
