Bare Metal Dual Core Design Based on Domestic ZYNQ
When reading and writing embedded multimedia card(eMMC)on ZYNQ chip bare met-al,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 stud-ying 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 do-mestic ZYNQ architecture is proposed.Without the participation of the operating system,the re-sources of the two cores of PS terminal can be simultaneously scheduled and the functions of eM-MC 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 operat-ing systems,which has been verified in practical projects.
