摘　　要：为解决当前Forth堆栈处理器架构不支持多任务并发和事件实时响应等问题,提出一种快速低切换开销的Forth堆栈处理器架构。在现有Forth堆栈处理器架构的基础上,引入新的指令、定时器、中断机制以及采用多任务堆栈技术,使得该架构支持实时多任务的运行。实验结果表明,基于堆栈处理器架构的Forth实时多任务调度支持多任务运行,与当前基于寄存器处理器的Forth实时多任务调度相比,实时任务响应、任务上下文切换和最大关中断等时间均明显缩短。To solve the problems that the current Forth stack processor does not support multi-task concurrency and event real-time response,a fast and low switching overhead Forth stack processor architecture was proposed.Based on the existing Forth stack processor architecture,new instructions,timers,interrupt mechanisms,and multitasking stack technology were introduced,real-time multitasking was then supported.According to experiments,the Forth real-time multitasking scheduling under stack processor architecture supports multitasking.Compared with the current Forth real-time multitasking scheduling based on the register processor,the proposed mothed significantly shortens the real-time task response,task context switching,and maximum interruption.
