适用MCU: TI MSP430 5XX 适用ucos-ii版本：2.86 编译环境：IAR4.11B 主要的工作： 在MICRIUM网站上430移植代码的基础上进行了修改：5XX系列PC寄存器为20位，堆栈的宽度仍为16位，因此在对PC和SR的压栈处理上做了修改；另外在汇编程序里调用HOOK函数的CALL XXX 改成 CALLA XXX

Input : A set S of planar points Output : A convex hull for S Step 1: If S contains no more than five points, use exhaustive searching to find the convex hull and return. Step 2: Find a median line perpendicular to the X-axis which divides S into SL and SR SL lies to the left of SR . Step 3: Recursively construct convex hulls for SL and SR. Denote these convex hulls by Hull(SL) and Hull(SR) respectively. Step 4: Apply the merging procedure to merge Hull(SL) and Hull(SR) together to form a convex hull. Time complexity: T(n) = 2T(n/2) + O(n) = O(n log n)

RS_latch using vhdl, When using static gates as building blocks, the most fundamental latch is the simple SR latch, where S and R stand for set and reset. It can be constructed from a pair of cross-coupled NOR (Not OR) logic gates. The stored bit is present on the output marked Q. Normally, in storage mode, the S and R inputs are both low, and feedback maintains the Q and Q outputs in a constant state, with Q the complement of Q. If S (Set) is pulsed high while R is held low, then the Q output is forced high, and stays high when S returns to low similarly, if R (Reset) is pulsed high while S is held low, then the Q output is forced low, and stays low when R returns to low.

Reconstruction- and example-based super-resolution (SR) methods are promising for restoring a high-resolution (HR) image from low-resolution (LR) image(s). Under large magnification, reconstruction-based methods usually fail to hallucinate visual details while example-based methods sometimes introduce unexpected details. Given a generic LR image, to reconstruct a photo-realistic SR image and to suppress artifacts in the reconstructed SR image, we introduce a multi-scale dictionary to a novel SR method that simultaneously integrates local and non-local priors. The local prior suppresses artifacts by using steering kernel regression to predict the target pixel from a small local area. The non-local prior enriches visual details by taking a weighted average of a large neighborhood as an estimate of the target pixel. Essentially, these two priors are complementary to each other. Experimental results demonstrate that the proposed method can produce high quality SR recovery both quantitatively and perceptually.

Software Radio (SR) is one of the most important emerging technologies for the future of wireless communication services. By moving radio functionality into software, it promises to give flexible radio systems that are multi-service, multi- standard, multi-band, reconfigurable and reprogrammable by software. Today’s radios are matched to a particular class of signals that are well defined bytheircarrierfrequencies,modulationformatsandbandwidths.Aradiotransmitter today can only up convert signals with well-defined bandwidths over defined center frequencies, while, on the other side of the communication chain, a radio receiver can only down convert well-defined signal bandwidths, transmitted over specified carrier frequencies.

近年来，随着电子技术的快速发展，使得低电压、大电流电路为未来主要发展趋势。低电压、大电流工作有利于提高工作电路的整体功率，但同时也给电路设计带来了新的问题。传统的变换器中常采用普通二极管或肖特基二极管整流方式，在低压、大电流输出的电路中，应用传统二极管整流的电路，其整流的损耗比较大，工作效率比较低。一般普通二极管的压降为1.0-1.3V，即便应用压降较低的肖特基二极管（SBD），产生压降一般也要有0.5V左右，从而使整流的损耗增加，电源的工作效率降低，己经不能满足现代开关电源高性能的需求。因此，应用同步整流（SR）技术可达到此要求，即应用功率MOS管代替传统的二极管整流。由于功率MOS管具有导通电阻很低、开关时间较短、输入阻抗很高的特点，很大程度的减少了开关功率MOS管整流时的损耗，使得工作效率有一个显著提高，因此功率MOS管以成为低压大电流功率变换器首选的整流器件。要想得到经济、高效的变换器，同步整流技术与反激变换器电路结合将会是一个很好的选择。反激变换器拓扑电路的优点是电路结构简单、输入与输出电气隔离、输入、输出工作电压范围较宽，可以实现多路的输出，因而在高电压、低电流的场合应用广泛，特别是在5~200W电源中一般采用反激变换器。
