ab: Summary: In order to inspect the size and defects of elastomer workpiece in
    real-time, a video preprocessing IP core based on Processor Local Bus
    (PLB) was proposed and implemented. The structure of IP core and the
    hardware implementation of convolution were investigated. LOG filter
    was designed by System Generator, and ultimately the edge detection
    algorithm was implemented on Field Programmable Gate Array (FPGA). The
    experimental results indicate that compared to the traditional
    implementation of edge detection by software, method of IP core
    achieves higher speed, and needs only 40 ms. It can satisfy the
    requirement of online inspection system of elastomer workpiece in
    real-time video preprocessing.
