A SoC design and implementation of dynamic image edge detection based on the LEON3 open source processor

A SoC design of dynamic image edge detection system is implemented based on the LEON3 open source soft-core processor in this paper. Sobel edge detection algorithm is selected and designed as an IP core and embedded to the SoC through the interconnect interface AMBA AHB bus. A D5M camera interface IP core is also designed to collect and transfer dynamic image data. The SoC is implemented on FPGA and the dynamic image edge detection IP is simulated by Modelsim and tested within the LEON3 SoC platform. Comparing to the existing dynamic image edge detection system based on microcontroller or DSP, results indicate that this special SoC could fully shows its advantage in high-speed and flexibility. Also the method this paper presents to design a SoC using AMBA AHB bus in the LEON3 architecture is reliable and referable.
