摘　　要：当ZYNQ芯片裸机读写嵌入式多媒体存储卡(eMMC)时,CPU会被大量占用,从而导致CPU性能严重消耗,某些对CPU性能要求较高的场景无法正常使用。通过对ZYNQ芯片处理系统(PS)端内部的组成架构进行研究,并结合其运行模式特点,提出了一种基于国产ZYNQ架构的裸机双核运行方式,在没有操作系统参与的条件下,可同时对PS端的双核进行资源调度并实现eMMC的读写等功能,并可在此基础上扩展到四核,极大提高了国产ZYNQ芯片在无操作系统参与的情况下对资源的利用率,并在实际项目中得到了实践验证。When reading and writing embedded multimedia card(eMMC)on ZYNQ chip bare metal,the CPU will be heavily occupied,which results in severe CPU performance consumption,so it cannot be used normally in some scenarios with high requirements to CPU performance.By studying the internal composition architecture of the processing system(PS)end of the ZYNQ chip and combining its operating mode characteristics,a bare metal dual core operation mode based on domestic ZYNQ architecture is proposed.Without the participation of the operating system,the resources of the two cores of PS terminal can be simultaneously scheduled and the functions of eMMC reading and writing can be realized,which can be extended to four cores on this basis.It greatly improves the resource utilization rate of domestic ZYNQ chips without the involvement of operating systems,which has been verified in practical projects.
