| Abstract (English): |
In order to improve the real-time performance of the operating system, the PPC460 processor is accelerated by hardware. The core code of PPC460 processor architecture is transplanted by using FPGA, the original SRAM space is modified to DPRAM and reinforced, the task control block (TCB) module is added to accurately locate and monitor the task status and stack information, and the original serial push stack and pop stack mode is modified to parallel simultaneous in and out stack mode when the task scheduling occurs in the operating system. The test results show that the method effectively realizes the sub microsecond design of task switching for PPC460 processor, and greatly improves the real-time and anti-interference ability of processing complex applications.
