Abstract
A system, method, and computer product for high-speed multiplication of binary numbers. A multiplier X is first encoded, and the encoded multiplier is then used in a multiplication process that yields the product. The encoding is performed in a manner that allows the actual multiplication process to proceed quickly. X is copied into a variable Z. Z is then manipulated to form the coded version of the multiplier. The bits of the multiplier X are read two at a time, starting with the least significant two bits. If the bit pair XXis equal to 11, then 1 is added to Z. The process continues for successive non-overlapping pairs of bits, until the most significant three bits of X are reached. These last three bits are encoded using a table look-up process.
