This makes md32 more powerful in multi - media signal processing . the main contents and innovative points in this paper include : define an instruction component and partition model . conception of orthogonal instruction set is presented based on the instruction component formula 通过对比不同的划分方法，合理安排流水线中指令的执行动作，最终确定出满足系统频率和时序要求的md32流水结构，使得risc dsp指令通过统一的流水安排融合在一起。
