Abstract
Aiming at the Zynq UltraScale+ MPSoC hardware platform, a simple AMP scheme is proposed by analyzing and comparing the existing asymmetric multi-processing (AMP) architecture schemes to realize one CortexA53 core running Linux operating system, and the other three CortexA53 cores running bare-metal system.This article starts with the analysis of the multi-core startup mechanism, realizes a Linux user mode dynamic loading multi-core program, designs a multi-core supervision module to solve the multi-core abnormal problem, and improves the stability of the system application.The test results show that the multi-core dynamic loading and startup function implemented by this solution is reliable, can meet high-performance, real-time control application requirements of power system industrial control equipment, which effectively improves the flexibility of system design, and has good engineering application value.
