Combining Serialisation and Reconfiguration for FPGA Designs

摘要

This paper describes a tool framework and techniques for combining serialisation and reconfiguration to produce efficient designs. Convolver and matrix multiplier designs are examined. Several optimisation techniques, such as restructuring and pipeline morphing, are presented with an analysis of their impact on performance and resource usage. The proposed techniques do not require the basic processing element to be modified. An estimate of the performance of the serial designs is given when mapped using distributed arithmetic and constant multiplier cores onto a Xilinx Virtex FPGA.
