Abstract
This paper presents how a ARM7 was designed by repeated adding group-instructions and the system was verified in a self-developed FPGA board. This ARM7 was then connected with a CMOS image capturing and processing unit (IPU) implemented in other FPGA board. ARM7 now become a microcontroller for this IPU. IPU integrates image capturing, convolution and sorting in FPGA to perform 3-stage pipelined operations to seed up system operations. Convolution and sorting help further filter out the Fixed Patten Noise (FPN) and dark current noise in CMOS image sensor and result in better image qualities. The FPGA board with ARM7 and IPU could be used for teaching CPU design, controller design and a system-on –chip (SoC) design since all circuits are in a single FPGA chip.
