Bit-serial multiplier for FPGA applications

摘要

A Field-Programmable Gate Array (FPGA) implementation of a multiplier topology can provide a considerable increase in computation performance and cost benefit as compared to other approaches, particularly for large bit widths (e.g., for multiplication of large-bit numbers). A lack of sufficient input/output (I/O) ports on the FPGA for a particular bit width can be remedied by implementing large-bit number multiplications in a bit-serial fashion. The bit-serial multiplier topologies described herein can provide a relatively small footprint as compared to other approaches. An FPGA-implemented bit-serial multiplier can improve operation of a computing system, for example, by offloading binary multiplication operations from a general-purpose processor.
