嵌入式系统低功耗软件技术研究
Study of Embedded System Low-Power Software Technology
摘要
Abstract
There is a research field for iow power technology that can't be mentioned only by the hardware design,so then using lowpower software technology can reduce system power consumption. From the software perspective, according to changes in processor load and idle mode, and taking full advantage of LCD electrical characteristics, the algorithm, using dynamic power management and dynamic voltage management combined, is put forward to reduce LCD power consumption. Furthermore, Operation Replacement and Optimization Instruction Sequence are used to analysis and research of matrix wansformation algorithm frequently using in graphics and image processing and give the low power strategy decreasing 73.9％ energy. According to low-power algorithms and strategies, it gives the conclusion and further research direction.关键词
