| Abstract: | The SD card controller IP core is designed through analyzing SD card physical layer specification and Avalon bus specification. The driver library is programmed by C running on Nios II processor. This controller is integrated into a embedded monitoring system by using custom component technology for application testing. The practical tests have shown that the design has advantages in convenience, high integration, fast and reliable data transmission and ensures real-time and reliable data storage in monitoring system. |
| Keywords: | FPGA SD card custom component monitoring system SD controller |
