This sample displays a basic integer calculator powered by the 8051 microcontroller. Although Keil C51 has a full floating point math library the evaluation version is restricted to 2k of object code, so we have constrained this sample to integer maths in order to fit within this limit. The program for this design was written in C using the Keil uVision 2 IDE for which Proteus VSM provides a Debug Monitor driver. Instructions for configuring Proteus to run in conjunction with the Keil environment can be found by editing the 8051 microcontroller on the schematic (point at it and press CTRL-E) and then clicking on the help button on the Edit Component dialogue form.

The main features of the considered identification problem are that there is no an a priori separation of the variables into inputs and outputs and the approximation criterion, called misfit, does not depend on the model representation. The misfit is defined as the minimum of the l2-norm between the given time series and a time series that is consistent with the approximate model. The misfit is equal to zero if and only if the model is exact and the smaller the misfit is (by definition) the more accurate the model is. The considered model class consists of all linear time-invariant systems of bounded complexity and the complexity is specified by the number of inputs and the smallest number of lags in a difference equation representation. We present a Matlab function for approximate identification based on misfit minimization. Although the problem formulation is representation independent, we use input/state/output representations of the system in order

A Matlab toolbox for exact linear time-invariant system identification is presented. The emphasis is on the variety of possible ways to implement the mappings from data to parameters of the data generating system. The considered system representations are input/state/output, difference equation, and left matrix fraction. KEYWORDS: subspace identification, deterministic subspace identification, balanced model reduction, approximate system identification, MPUM.

就像在嵌入系统中使用C语言替代汇编一样,在嵌入系统中使用RTOS是大势所趋。原因主要是现在在大多数情况下编程效率比执行效率重要(单片机便宜嘛)。但纵观51的RTOS,keil c51 所带的RTX Full 太大(6k多),且需要外部ram,又无源代码,很多时候不实用。RTX Tiny虽然小(900多字节),但是任务没有优先级和中断管理,也无源代码,也不太实用。而ucosII虽有源代码,但是它太大,又需要外部ram,所有函数又必须是重入函数,用在51这类小片内RAM的单片机上有点勉强。于是,我借鉴ucosII和RTX Tiny编写了Small RTOS 51,虽然它为51系列编写,但是它还是比较容易移植到其它CPU上。

Get more out of your legacy systems: more performance, functionality, reliability, and manageability Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts.

给VC增加多标签功能,每个打开的文件显示为一个标签,可以快速切换文件.安装后解压语言文件到安装目录,可以实现多语言切换. === === "Window Tabs" (WndTabs) is an add-in for Microsoft Visual C++ v6 family of products (VC5, VC6, eVC3, eVC4 and Visual Fortran). It adds a docking bar of tabs reflecting all of the opened windows in the workspace. You can switch between the windows by simply clicking on the tab. The tabs have extensive right-click context menus full of useful functions.
