摘　　要：TI的C66X多核DSP拥有丰富的接口资源,单片集成了高速串行接口AIF2、SGMIL、PCIe和SRIO等,能够非常方便地进行高速数据传输和系统扩展,其中PCIe接口应用最广,它广泛地应用在信号处理、通信、医疗、自动化等领域。本文阐述了PCIe接口的Inbound和Outbound地址映射寄存器配置方法、PCIe的中断安装过程和EDMA的传输配置与实现过程。用该方法可快速完成多核DSP的PCIe接口配置与编程,方便PCIe接口的推广和应用。TI C66 X multi-core DSP has rich interface resources, which integrates high speed serial interfaces AIF2, SGMIL, PCIe,SRIO and so on in a single chip, can be very convenient for high-speed data transmission and system expansion. Among them,the PCIe interface is the most widely used; it is widely used in signal processing, communication, medical treatment, automation and other fields. This paper describes the configuration method of PCIe interface＇s Inbound and Outbound address mapping register,the installation of PCIe interrupt and the transmission configuration and implementation process of EDMA. With this method, the multi-core DSP＇s PCIe interface configuration and programming can be quickly completed, to facilitate the promotion and application of PCIe interface.
