Multiprocessor real time edge detection using FPGA IP cores

Real time edge detection is required in many embedded systems where execution speed is critical. This task is intensely computational but highly parallelizable and, in order to satisfy the real-time requirements, using multiprocessor-based embedded systems can be a viable solution. In this paper we propose a MPSoC hardware and software co-design method for real-time Sobel edge detection using FPGA and IP blocks. The experiments we performed show a speed-up of 1.71 in the case of a multiprocessor system with two processors and a speed-up of 3.48 in the case of a multiprocessor system with four processing cores, versus a single processor system.
