As the single-chip processing speed and ram resource constraints, generally do not use floating-point, and will use all parameters of all integers, computing the final 2 and then divided by a N-th power of data (equivalent to shift), similar fixed-point computation can be greatly enhanced speed of operation, according to the different requirements of control precision, when high precision, the attention to retain the shift caused by the balance , do a good job in the balance of compensation. This procedure is commonly used algorithm pid basic structure does not contain input and output part of treatment.

Description: 基于CUDA的高性能图像处理算法。着重介绍CPU和CUDA的计算能力，并详细介绍图像处理的背景以及几种操作的原理。在经过实验之后，对比CPU的计算能力可以发现，CUDA在并行处理数据的能力非常强大。由此可知，在图像处理的应用中，CUDA将大有可为。然而Hough变换的性能提升并不明显，其中的原子操作导致线程的排队，大幅度降低了线程并发性能，从而使得CUDA并行运算的优点不能显示出来，此问题的解决，有赖于对Hough变换并行算法的更深入研究。-CUDA-based high-performance image processing algorithms. Focuses on the computing power of CPU and CUDA, and detail the background of image processing and several operating principles. After experiments, comparing CPU' s computing power can be found, CUDA' s ability to process data in parallel is very strong. It can be seen in image processing applications, CUDA will be promising. Hough transform performance, however not obvious, which led to the thread queue atomic operations, significantly reduce the thread concurrency, which makes the advantages of CUDA parallel computing can not be displayed to solve this problem, parallel algorithm depends on the Hough transform more in-depth study.

Description: 在《温度计_基本原理》程序中，已经实现了一个温度测量和显示的系统，但因为采样速率很快，且对基准源不加控制，耗电很大(800uA左右)。本例中，将温度采集速度降到1秒一次，且采样间隙时间不仅关闭基准源，还让CPU进入LPM3休眠状态，大大节省了耗电。该程序功耗仅10uA左右，可用纽扣电池长期运行(2年)。实际上对于环境温度1秒1次采样仍属浪费，如果降到5秒一次，功耗可下降到4uA左右(CR2032电池工作5年)。按KEY3后，CPU进入LPM4，功耗下降到0.1uA，这是一种常用的不断电的关机方法。同时，该程序示例了如何例用程序库快速的完成开发任务。-In the "basic principles of the thermometer _" program, has achieved a temperature measurement and display system, but because the sampling rate soon, and uncontrolled source of reference, a large power consumption (800uA or so). In this example, the temperature dropped to 1 second time acquisition speed, and the sampling time is not only close the gap reference source, but also allow CPU access to LPM3 sleep, significant savings in power consumption. 10uA power consumption is only about the program, the available long-running button batteries (2 years). In fact, for the ambient temperature 1 1 second sample is still a waste, if reduced to 5 seconds, power consumption can be reduced to around 4uA (CR2032 battery 5 years). After the press KEY3, CPU into LPM4, power consumption down to 0.1uA, which is a commonly used method for UPS shutdown. At the same time, the program example of how patients use the library to complete the development tasks faster.
