[0024] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings of the specification.
[0025] The Zynq chip is the Zynq dual-core series chip of Xilinx Company. It is composed of dual-core ARM (two Cortex-A9 in the picture) and FPGA. The dual-core ARM and FPGA are connected through the on-chip Advanced Extensible Interface (AXI) bus. Share external memory with FPGA. Internal hardware structure such as figure 1 Shown. The functions of a digital intelligent electronic device in the AMP mode are as follows: figure 2 As shown, high real-time tasks such as protection computing and SV / GOOSE message processing run on the bare running core, and functions such as man-machine interface and communication management run on the operating system core.
[0026] The ARM and FPGA cores are connected via the AXI standard bus. Configuration information is exchanged through registers, which is more flexible, but the rea...
