确立了多任务管理单元 MTU的设计方案 ,探讨了多任务管理的定义、数据结构 ,给出了微处理器多任务切换算法 ,提出了多任务管理单元 MTU细胞群结构。细胞群结构由细胞组成 ,每个细胞可进行一种测试并输出测试的布尔值给微程序控制器来控制微程序的转移。多任务管理单元 MTU的 RTL级 VHDL描述经 EDA工具 MENTOR GRAPHICS的综合与仿真验证了多任务管理单元 RTL级 VHDL描述的正确性与有效性。
The design scheme of multi-task management unit (MTU) was established. The definition and data structure of multi-task management was discussed. The multi-task switching algorithm was given and MTU cell structure of multi-task management unit was proposed. The cell population structure consists of cells, each of which can perform a test and output a test Boolean value to a microprogram controller to control the transfer of microprograms. RTL VHDL Description of MTU for Multitasking Management Unit The synthesis and simulation of MENTOR GRAPHICS by EDA tools verify the validity and validity of RTL VHDL description of multitasking management unit.
