Abstract

Reconfigurable Multiplier Blocks (ReMB) offer significant complexity reductions in multiple constant multiplications in time-multiplexed digital filters. In this paper the ReMB technique is employed in the implementation of a half-band 32-tap FIR filter on both Xilinx Virtex FPGA and UMC 0.18micro m CMOS technologies. Reference designs have also been built by deploying standard time-multiplexed architectures and off-the-shelf Xilinx Core Generator system for the FPGA design. All designs are then compared for their area and delay figures. It is shown that, the ReMB technique can significantly reduce the area for the multiplier circuitry and the coefficient store, as well as reducing the delay.
