硬件实时操作系统信号量管理的设计与实现

信号量管理是操作系统中频繁运行的程序段之一。为提高实时操作系统RTOS的响应能力,提出了基于FPGA硬件实现信号量管理的设计方案。采用片内寄存器实现事件控制块(ECB)、映射表等存储结构,使用组合逻辑电路实现信号量管理模块,提高了信号量创建、删除及P/V操作的执行速度。

Design and realization of semaphore management in hardware RTOS

The semaphore management is a program segment which runs frequently in the operating system,in order to enhance the response capability of the real-time operating system RTOS,the design solution that implement the semaphore management based on FPGA is put forward.The storage structure,event control block(ECB) and mapping table,are realized by on-chip registers;The semaphore management is realized by combinational logic circuit;Both of them bring about high speed in creating semaphore,deleting semaphore and ...
