Abstract :
We propose a novel architecture for variable comparator named RPCA (Reconfigurable Parallel Comparation Architecture) making full use of the reconfigurability of FPGA. In the RPCA, an appropriate comparator to each task can be chosen and implemented under the speed/data-size tradeoff. An RPCA-based pack-filter prototype using XILINX XCV300E-6PQ240C and RealTeK RTL8201BL is developed and filtering speed of 120ns for 128 IPs and 1,360ns for 2,048 IPs are obtained under the speed/data-size trade-off.
