Research on verification framework of image processing IP core based on real-time reconfiguration

The verification of IP core with image processing algorithm is important for SoC and FPGA application in the field of machine vision. This paper proposes a verification framework with general purpose, real-time performance and agility for IP core with image processing algorithm by using heterogeneous platform composed of ARM and FPGA. In the verification framework, the Gigabit Ethernet communication between PC and ARM is established. The FPGA is used to build the data bus to be compatible with multiple types of images, and combine with a partial reconfiguration to achieve fast iteration of IP cores of the algorithm to be verified. The validation framework is reusable for the algorithm IP core, and the deployment speed of the IP cores to be verified is 25 times faster than global reconfiguration. Compared with the existing FPGA verification technology, it has better reusability, shorter verification cycle, more targeted test stimulus, and faster deployment of IP cores to be verified.
