An embedded processing system for image data compression and storage

Electromagnetic interference, shock and vibration under adverse conditions are critical problems for the design of embedded processing system, especially in the limited spaces. In addition, processing and transferring of large-scale image data are also important to the system. Therefore, in this paper an image data processing and storage system is designed, in which an ETX-CPU is used as the main module and a Virtex-II family FPGA acts as the processing core, at the same time, a well-appointed power processing circuit is designed to ensure the correctness of the system. In the end, CADENCE PCB layout design tools are used to solve the signal integrity problems of the system.
