In order to solve the large amount of data storage problem in embedded system, a Nand Flash controller was designed based on the research of Nand Flash and CoreConnect bus. The controller integrated a standard PLB with DCR bus interface, using an efficient ECC algorithm for error detection and correction function, using a method of automatic filling ECC to improve write operation speed. The controller was applicated in a video acquisition system. The result shows that the controller operates correctly, and has a read/write speed of up to 18 MB/s and 35 MB/s, and can satisfy the real-time access to video data.
