An optimized design of microprogrammed control unit including the predicted unit 支持預(yù)取的微程序控制器的一種優(yōu)化設(shè)計(jì)
The author is absorbed in research on technology of coprocessor design . in the floating - point addition the paper proposes a carry chain of dynamic and static mixed circuits and a good balance between speed and area of predicting leading - zero logic circuits , considering algorithm and construction of logic circuits . an approach of micro program controller design for coprocessor is put forward and a test bench is given to verify its function 筆者研究協(xié)處理器的設(shè)計(jì)技術(shù),在浮點(diǎn)加法器中提出動(dòng)態(tài)與靜態(tài)結(jié)合設(shè)計(jì)進(jìn)位鏈的方案以及前導(dǎo)零預(yù)測(cè)面積與速度的折衷方法;在微程序控制器的設(shè)計(jì)中提出一種協(xié)處理器微程序控制器的設(shè)計(jì)方法,并且給出其功能驗(yàn)證的測(cè)試平臺(tái)。
A typical calculator chip from rcl semiconductor inc , c9821 , is referenced and developed . the chip of the calculator consists of several function units such as rc oscillator , power management module , microprogrammed control unit ( mcu ) , register group , lcd driver and keyboard interface 在硬件方面,在完成計(jì)算器的功能模塊劃分的基礎(chǔ)上,對(duì)包括rc振蕩器、電源模塊、 lcd顯示驅(qū)動(dòng)模塊、鍵盤接口、寄存器組、微程序控制器在內(nèi)的各個(gè)功能模塊的系統(tǒng)結(jié)構(gòu)和電路原理進(jìn)行了分析,掌握了它們的設(shè)計(jì)方法。
