Abstract:

Aiming at the current status of the single video signal source, a new design scheme of portable multi function video signal source system is proposed. Described in detail the hardware and software design of the signal source system scheme based on consideration of the portable, multi function, reliability, the equipment adopts the AMD APU chip platform, reduce the FPGA resource consumption, simplify the design of the hardware circuit and software supporting adopted modular design. Video signal source can provide a variety of standard test images, at the same time, according to specific requirements to produce a special standard or signal. The experimental results show that the system has good stability, high reliability and convenient use, and can meet the design requirements.
