But anyway, I don't see how using the 32x32=32 instructions can save any steps. If you use it with 32x16 data you are still going to get a 48 bit result and lose the upper 16 bits of that. You will still need a total of 3 multiplies to recover the lost bits and get the correct answer. -- Howard ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
