Mapping multi-mode circuits to LUT-based FPGA using embedded MUXes

Abstract

For some systems, a general-purpose FPGA solution tends to be large and slow. A reconfigurable solution is smaller and faster but has a delay associated with the reconfiguration. In this paper, embedded MUXes are used to achieve the performance of reconfiguration without the time penalty. For a CRC circuit an area reduction of 93% compared to a general-purpose solution and a reduction of 17-34% compared to similar software compiled systems is achieved.
