Adapting compilation techniques to enhance the packing of instructions into registers
The architectural design of embedded systems is becoming increasingly idiosyncratic to meet varying constraints regarding energy consumption, code size, and execution time. Traditional compiler optimizations are often tuned for improving general architectural constraints, yet these heuristics may not be as beneficial to less conventional designs. Instruction packing is a recently developed compiler/architectural approach for reducing energy consumption, code size, and execution time by placing the frequently occurring instructions into an Instruction Register File (IRF). Multiple IRF instructions are made accessible via special packed instruction formats. This paper presents the design and analysis of a compilation framework and its associated optimizations for improving the efficiency of instruction packing. We show that several new heuristics can be developed for IRF promotion, instruction selection, register re-assignment and instruction scheduling, leading to significant reduct...
