Power leakage constitutes an increasing fraction of the total power consumption in modern semiconductor technologies. Recent research efforts indicate that architectures, compilers, and software can be optimized so as to reduce the switching power (also known as dynamic power) in microprocessors. This has lead to interest in using architecture and compiler(More)
In this paper, we investigate the compiler transformation techniques to the problem of scheduling VLIW instructions aimed to reduce the power consumption on the instruction bus. It can be categorized into two types: horizontal and vertical scheduling. For the horizontal case, we propose a bipartite-matching scheme. We prove that our greedy algorithm always(More)
