在深入了解Flash存儲(chǔ)器的基礎(chǔ)上，采用單片機(jī)自動(dòng)檢測(cè)存儲(chǔ)器無(wú)效塊。主要通過(guò)讀取每一塊的第1、第2頁(yè)內(nèi)容，判斷該塊的好壞，并給出具體的實(shí)現(xiàn)過(guò)程，以及部分關(guān)鍵的電路原理圖和C語(yǔ)言程序代碼。該設(shè)計(jì)最終實(shí)現(xiàn)單片機(jī)自動(dòng)檢測(cè)Flash壞塊的功能，并通過(guò)讀取ID號(hào)檢測(cè)Flash的性能，同時(shí)該設(shè)計(jì)能夠存儲(chǔ)和讀取1GB數(shù)據(jù)。 Abstract: On the basis of in-depth understanding the Flash chips，this paper designs a new program which using the SCM to detect the invalid block.Mainly through reading the data of the first and second page to detect the invalid block.Specific implementation procedure was given,and the key circuit schematic diagram and C language program code was introduced.This design achieved the function of using the MCU checks the invalid block finally，and increased the function by reading the ID number of Flash to get the performance of the memory.And the design also can write and read1GB data

ADO.NET in a Nutshell is the most complete and concise source of ADO.NET information available. Besides being a valuable reference, this book covers a variety of issues that programmers face when developing web applications or web services that rely on database access. Most examples use Microsoft s C# language. The book s CD includes an add-in to integrate the reference with Visual Studio .NET help files.

Every day, patches are created to cover up security holes in software applications and operating systems. But by the time you download a patch, it could be too late. A hacker may have already taken advantage of the hole and wreaked havoc on your system. This innovative book will help you stay one step ahead. It gives you the tools to discover vulnerabilities in C-language-based software, exploit the vulnerabilities you find, and prevent new security holes from occurring.

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).
