Abstract :
The application based on FPGA chip are more and more popular especially for speech processing and image processing. At the same time, the application needs more memory except for on-chip memory to store additional data. To meet the requirements of external memory for FPGA-based systems, the writing/reading SD card system based on FPGA is designed and implemented. In this thesis, after analyzing the control principle of SD cards and SD card systems, the structure of 1-bit SD card transfer mode system is designed. The hardware design and implementation is completed on the QuartusII platform. The software including SD card driver and the corresponding control program is developed on the NiosII platform. At last, the system is tested and the result shows that the performance of the entire system can run stably and reliably, reach to the effect anticipative.
