Abstract
- In this paper, we proposed an architecture of embedded systems for high-frame-rate real-time vision on the order of 1000 f/s, which achieved both hardware reconfigurability and easy algorithm implementation while fulfilling performance demands. The proposed system consisted of an embedded microprocessor and field programmable gate arrays (FPGAs). A coprocessor consisting of memory units, direct memory access controller units, and image processing units were implemented in each FPGA. While the number of units and functions are reconfigurable by reprogramming the FPGAs, users can implement algorithms without hardware knowledge. A descriptor method in which the central processing unit gave instructions to each coprocessor through a register array enabled task-level parallel processing as well as pixel-level parallel processing in the processing units. The specifications of an evaluation system developed based on the proposed architecture, the results of performance evaluation, and application examples using the system were shown.
