摘要
P2020作为一种高性能嵌入式处理器广泛应用于航空电子设备。文章针对使用P2020处理器结合FPGA实现ARINC429接口时,存在处理器局部总线与ARINC429组件数据线宽不匹配问的题,提出了一种16位线宽与32位线总线转换算法,并且通过功能仿真和数据实测的方式验证了该算法的可行性。
As a high-performance embedded communication processor, the P2020 is widely used in avionic equipments. There is an incompatibility with data bus width between ARINC429 FPGA component data interface and enhance local bus in P2020 platform. This article proposed a new bus width transform algorithm to realize using 16-bit width data bus to access 32-bit width device, and verified the effectiveness of the method.
