Isa is divided into three parts according to the design consideration of md32 . rich addressing and operation modes are supported in md32 isa . risc / dsp pipeline partition rules are given based on the relations between instruction set and data path design 在md32設(shè)計(jì)中采用了具有自身特色的設(shè)計(jì)方法,探索出一套面向risc dsp指令結(jié)構(gòu)的微結(jié)構(gòu)設(shè)計(jì)原則和方法,如并行設(shè)計(jì)、內(nèi)部流水設(shè)計(jì)、集中控制等。
