Develop the simulation environment for full - instruction simulation of the microcontroller ; the result of this paper shows that user risc core method to design the microcontroller is an efficiently way to improve the system performance 對(duì)應(yīng)于每一條原mcs51指令,都有一條或者多條新的risc51ipcore的單周期指令來實(shí)現(xiàn)其功能。
The simulation of the addressing mode provides the possibility for the instruction simulation , and the simulation of the interrupt , timer and serial port lets the simulator implement the functions of the interrupt , timer and serial like a processor , and the program control simulation provides the possibility for running the program . this function is also the base for debugging program , which can set step running mode , set break points by using this program 尋址方式的模擬為指令的模擬提供了可能,中斷、定時(shí)器和串行口的模擬使模擬器可以象處理器一樣完成中斷功能、定時(shí)功能和串行通訊功能,程序控制的模擬為程序運(yùn)行提供了可能,這一功能又是調(diào)試程序的基礎(chǔ),通過這個(gè)程序程序可以單步執(zhí)行,設(shè)斷點(diǎn)執(zhí)行。
