【摘要】：依据ATA6协议,在FPGA上设计对IDE硬盘的控制模块,同时使用Xilinx的多端口内存控制器MPMC IP核,实现能够访问外部DDR2_SDRAM的NPI接口控制器。在此基础上,利用嵌入式FPGA开发环境,设计顶层控制IP核,完成硬盘控制器与NPI接口的有效衔接。在Micro Blaze的控制下,数据在硬盘与DDR2_SDRAM之间直接高速传输,实现了高性能DMA控制器的功能,从而提高了主机CPU利用率。设计在Xilinx的XUPV5_LX110T开发平台得到了验证。
[Abstract]:According to the ATA6 protocol, the control module of the IDE hard disk is designed on the FPGA, and the MPMC IP core of the Xilinx multi-port memory controller is used to realize the NPI interface controller which can access the external DDR2_SDRAM. On this basis, the top control IP core is designed by using the embedded FPGA development environment, and the interface between the hard disk controller and the NPI is effectively connected. Under the control of Micro Blaze, the data is transmitted directly between the hard disk and DDR2_SDRAM at high speed, which realizes the function of high performance DMA controller, and improves the utilization rate of host CPU. The design is verified in the XUPV5_LX110T development platform of Xilinx.
