1. Introduction
At present, the needs for speed and accuracy of image processing systems have become more increasingly high, and the sampling of data is growing. Hardware resources and the environment is generally more demanding in the embedded system. The memory of embedded microprocessors and microcontrollers is generally no. 1arge. In order to achieve the DSP (Digital Signal Processing) systems run independently, the high-capacity storage medium is needed to save the sampling results. The capacity of Flash on-board is generally small, the data will be lost after SDRAM power-down, and they can not easily transfer the data to a computer. This paper presents a CF card to use as a data storage medium storing large amount of data. [1]
