摘要:This paper reviewed the design of a general purpose AHB-DMA controller which has two channels to perform read/write operations between the memory and customizable interface (SPI, I2C, USB or SDIO etc.). Each DMA channel enables movement of data from a source AHB address to the IP or IP to the destination AHB address, for a given programmed count. When the programmed bytes (data) are transferred to/from the system memory, an “End of transfer interrupt” is generated by the DMA for each channel
