Latest Patents
Robert C. Letteney holds a patent for a "High speed multiplier using carry-save/propagate pipeline with sparse." This invention minimizes latch requirements and I/O pin requirements between chips by employing a new configuration. The apparatus iteratively adds four multiples of a multiplicand in a stage of 4-2 carry save adders, which then feed four-bit parallel adders. Each of these adders has four sum outputs and a carry output from the highest order bit position. Only the sum outputs are latched and subsequently fed to a carry propagate adder on each iteration for addition to the previous partial products. The design ensures that only the single carry output from each of the 4-bit parallel adders needs to be latched and then fed to another 4-bit parallel adder. This innovative approach enhances the efficiency of high-speed multiplication.
