Abstract: Conventional high performance computer connections are electron-based systems, which require the memory packages to be as close as mechanically possible to the computation engine. Low power and high bandwidth long distance communication, e.g. photonic or electronic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication.

Abstract: Conventional high performance computer connections are electron-based systems, which require the memory packages to be as close as mechanically possible to the computation engine. Low power and high bandwidth communication, e.g. photonic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication and augment existing memory systems to allow them to be both high capacity and high bandwidth simultaneously.

Abstract: An 8×8 binary digital multiplier reduces the height of partial product columns to be no more than 7 bits high. The six 7-bit high middle columns are each input to a (7:3) counter. An ascending triangle compressor operates on the lesser significant bit columns. A descending triangle compressor operates on the greater significant bit columns. The counter and compressor outputs are combined for a final stage of compression, followed by partial product addition.
