摘要:
嵌入式系统低功耗设计中有硬件技术无法涉足的空间，可通过低功耗软件技术实现降低系统功耗的目的。针对液晶显示器（LCD）电气特性，从软件角度，综合运用动态电源管理技术和动态电压管理技术，根据处理器负载变化趋势和对空闲模式计时的思想，给出了降低液晶显示器功耗的算法和策略；利用优化编译技术中的操作替换和指令排序方法，分析和研究图形图像处理中常见的矩阵变换算法，给出了低功耗策略和验证节能73．9％。并就低功耗软件技术算法和策略给出了结论和提出了下一步研究的方向
Abstract:
There is a research field for low power technology that can＇t be mentioned only by the hardware design, so then using low-power 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 transformation 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
