摘要
Abstract
The SoPC technology proposed by Altera is introduced.A SD card controller that contains both the Master and Slave ports was designed according to Avalon bus specification of SoPC system.It supports the interruption but need not perform CPU intervention, so the SD card RW speed is improved greatly.The core technologies of the design are the time-sequence control of SD card RW controller and the interface between Avalon-MM bus and Nias Ⅱ processor.The controller was validated on DE2 development platform of Terasic Technologies and a quick access of large amount of data was realized.It meets the needs of the general electronic products.关键词
