This document describes the uIP TCP/IP stack. The uIP TCP/IP stack is an extremely small implementation of the TCP/IP protocol suite intended for embedded systems running low-end 8 or 16-bit microcon-trollers. The code size and RAM requirements of uIP is an order of magnitude smaller than other generic TCP/IP stacks today.

很多嵌入式系统,特别是应用于图像处理与高速数据采集等场合的嵌入式系统,都需要高速缓存大量的数据。DDR(Double Data Rate,双数据速率)SDRAM由于其速度快、容量大,而且价格便宜,因此能够很好地满足上述场合对大量数据缓存的需求。但DDR SDRAM的接口不能直接与现今的微处理器和DSP的存储器接口相连,需要在其间插入控制器实现微处理器或DSP对存储器的控制。

tServer task executes functions at low priority (254). serverSend funtion is used to send a request to the tServer to execute a function at the tServer s priority. First tServer task executes the i() system call to print the summary of tShell task. Next an address exception is caused in tServer task by trying to execute a funtion at non-aligned word boundry. As a result SIGBUS signal is raised automatically. Signals (setjmp() and longjmp()) are used to allow the tServer task to recover gracefully from an address error exception. For more information about signals, please refer to sigLib manual pages.

The MATLAB coding style, project options and synthesis directives can have a significant effect on the final results. Knowledge about how a particular algorithm should be implemented in hardware can be reflected in the MATLAB code to improve the results. In doing so, the MATLAB loses a bit of its abstraction but the lower-level MATLAB will infer the desired architecture into the device.

CCS编程环境 使用的是汇编加C的混合编程方法: The programme of the Correlation Algorithm. Using INT2 to get the input signal. Array x, in first step, is the input signal produced by programme, in next step, is the input signal get from A/D, the length is 128, 32-bit floating point. Array y, in first step, is the input signal produced by programme, in next step, is the input signal get from A/D, the length is 128, 32-bit floating point. Array cor is the Correlation result, the length is 255, 32-bit floating point.

how to extend an OLE DB consumer template class and make it much easier to use in applications. I had also explained how you can utilize the power of C++ exception-handling feature to make your work easier, especially in error handling. It was just a small class in my last article.

%CHECKBOUNDS Move the initial point within the (valid) bounds. % [X,LB,UB,X,FLAG] = CHECKBOUNDS(X0,LB,UB,nvars) % checks that the upper and lower % bounds are valid (LB <= UB) and the same length as X (pad with -inf/inf % if necessary) warn if too long. Also make LB and UB vectors if not % already. % Finally, inf in LB or -inf in UB throws an error.

Writing Your First ASP Application ( Quick Start ) (Page 1 of 8 ) There are many tutorials out there that show you how to program in ASP. Some of them are good, and some are bad. Some of them are downright terrible. In any case, you ve read a bit about ASP and now you are ready to build your first application. But where do you start? In my own experience, I have found that I find it easier to learn something if I actually work with it hands-on. Just reading a book or documentation doesn’t give you the practical knowledge you need to be able to rush off and start creating applications. In this article, I will discuss the creation of a very simple application. I will cover what the application will do, how we will approach writing it, demonstrate in code how we will do it, and discuss additional features that could be added to it.
