A Novel FPGA-Based 2-D Convolver
-
Abstract
This paper presents a novel 2-D convolver targeted at field programmable gate array (FPGA) .The design features its low external memory bandwidth of 1 pixels/clock, and consumes comparatively little on-chip resources, reducing 95% of that compared with traditional convolvers.Also, it brings flexibility to system design by configurable throughput rate based on the real-time requirements.When implemented on Altera EP4SGX230KF40 FPGA, the throughput rate could reach up to 90 Mpixels/s for 5×5 image convolution, and it could satisfy most real-time image processing applications.
