Abstract
This paper presents a procedure to generate energy-efficient code for the Motorola DSP56K processor based on increasing the packing efficiency and minimizing the number of address instructions. The key features are a novel scheduling algorithm that reduces the dependencies between instructions, a register allocation algorithm that spills variables based on their packability, and an address code generation algorithm that minimizes the number of additional instructions. The size of the code generated by this procedure is on the average 45% (25%) smaller than that generated by Motorola's g56 K (SPAM).
本文提出了一种基于提高封装效率和减少地址指令数量的摩托罗拉DSP56K处理器的节能代码生成程序。其主要特点是一种新颖的调度算法，它减少了指令之间的依赖关系，一种寄存器分配算法，它根据变量的可包装性溢出变量，以及一种地址码生成算法，它最大限度地减少了额外指令的数量。这个过程生成的代码的大小平均比摩托罗拉的g56 K (SPAM)生成的代码小45%(25%)。
