Design of AHB-Based SD/SDHC/MMC Controller
-
Abstract
Based on analyzing SD (Secure Digital Card) card transport protocols, a design scheme of SD card controller is proposed in this paper.The designed controller can be used in real time data stream processing through the implement of an AHB (Advanced High-performance Bus) interface and a special DMA (Direct Memory Access) transfer mode.The controller has been FPGA (Field Programable Gate Array) -verified and satisfied the design goal completely.
