| Abstract: | The image acquisition hardware system designed in this paper, taking DSP and CPLD are as the core, has the functions of the acquisition and quick processing of the digital signal output by image sensor. It is composed of power supply module, DSP peripheral circuit, digital image processing module and CPLD logic control module. It has the merits of small vol- ume, low cost, flexible online programming, perfect real-time processing, etc. It can solve the practical application conflicts among the weight, size, cost, etc. It has the universality for amount of data which is less than 512 K×8 b. The debugging resuits show that the image acquisition system achieve the expected goal. |
