摘　　要：硬件化的实时任务调度器使用VHDL语言进行编写,使用组合逻辑电路和时序逻辑电路实现基于优先级的时间片轮转调度算法。由门电路搭建而成的硬件化调度器独立于内核之外,根据连接内核的数量,在编译时进行调整,同时对多个结构相同或不同的内核进行调度。内核只需要执行任务,不需要进行任务调度,以此来减轻对处理器的负担,提升操作系统的实时性和可靠性。The hardware based real-time task scheduler is written in VHDL language,and the priority based time slice rotation scheduling algorithm is implemented using combinational logic circuits and sequential logic circuits.The hardware scheduler built by the gate circuit is independent of the core.It adjusts at compile time according to the number of connected cores,and schedules multiple cores with the same or different structure.The kernel only needs to execute tasks and does not need to schedule tasks,so as to reduce the burden on the processor and improve the real-time and reliability of the operating system.
