基于ZYNQ的接收机平台设计与实现

针对传统DSP+FPGA等组合平台的接收机中出现的数据传输不稳定,传输速率慢的问题,提出了一种基于ZYNQ的接收机平台。首先,根据ZYNQ的异构架构特点,在PS与PL之间搭建一个协议转换通道;然后,在PL部分设计一个接口模块与协议转换通道对接,用于PS到PL的数据分流,或者切换PS要进行读操作的模块;最后,通过VIVADO自带的内嵌逻辑分析仪对该平台进行验证。测试结果表明,使用这种平台的导航接收机比传统的组合平台接收机数据传输速度更快,性能更稳定。

Platform Design Based on ZYNQ Software and Hardware Cooperative Application

Aiming at the problem of unstable data transmission and slow transmission rate in receivers of traditional DSP+FPGA combined platforms,a ZYNQ-based receiver platform is proposed. Firstly,according to the heterogeneous architecture characteristics of ZYNQ,a protocol conversion channel is set up between PS and PL. Then,an interface module is designed to be connected to the protocol conversion channel in the PL part,for data splitting from PS to PL,or switch the module for PS to read. Finally,the platform was verified by the built-in logic analyzer of ⅥⅤADO. The test results show that the navigation receiver using this platform has faster data transmission performance and more stable performance than the traditional combined platform receiver.
