在深入了解Flash存儲器的基礎上，采用單片機自動檢測存儲器無效塊。主要通過讀取每一塊的第1、第2頁內容，判斷該塊的好壞，并給出具體的實現過程，以及部分關鍵的電路原理圖和C語言程序代碼。該設計最終實現單片機自動檢測Flash壞塊的功能，并通過讀取ID號檢測Flash的性能，同時該設計能夠存儲和讀取1GB數據。
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

Abstract: This application note explains the hardware of different types of 1-Wire® interfaces and software examples adapted to this hardware with a focus on serial ports. Depending on the types of iButtons required for a project and the type of computer to be used, the most economical interface is easily found. The hardware examples shown are basically two different types: 5V general interface and 12V RS-232 interface. Within the 5V group a common printed circuit board could be used for all circuits described. The variations can be achieved by different populations of components. The same principal is used for the 12V RS-232 interface. The population determines if it is a Read all or a Read/Write all type of interface.
There are other possible circuit implementations to create a 1-Wire interface. The circuits described in this application note cover many different configurations. For a custom application, one of the described options can be adapted to meet individual needs.

A windows BMP file is a common image format that Java does not handle. While BMP images are used only on windows machines, they are reasonably common. Reading these shows how to read complex structures in Java and how to alter they byte order from the big endian order used by Java to the little endian order used by the windows and the intel processor.

ARM下 Implement matrix multiplication of 2 square matrices, with data read from an input file and printed both to the console and to an output file.
• Assume a file with correct data (no garbage, characters, etc.).
• you must check and provide appropriate execution for 2 extra cases, namely when the matrix size given is either “0” , or when the size is greater than the maximum handled of “5” . In these 2 cases you must implement the following behaviour:
o If size = 0, then print a message “Size = 0 is unacceptable” and continue by Reading the
next size for the next 2 matrices (if not end of file).
o If size >5, then print two messages: “Size is too big - unacceptable”. Then read and
discard the next (size2 ) integers and continue by Reading the next size for the next 2 matrices (if not end of file).

THIS is really two books in one: a tutorial and a reference manual for JDBC, the application programming interface that makes it possible for programmers to access databases from Java. The goal is to be useful to a wide range of readers, from database novices to database experts. Therefore, we have arranged the book so that information needed only by experts is separated out from the basic material. We hope that driver developers as well as application programmers and MIS administrators will find what they need. Because different sections are aimed at different audiences, we expect that few people will read every page. We have sometimes duplicated explanations in an effort to make Reading easier for those who do not read all sections.
This book will be most helpful to those who have some knowledge of the Java programming language and SQL (Structured Query Language), but one doesn t need to be an expert in either to understand the basic concepts presented here.

來自澳大利亞Qeensland大學的計算機視覺Matlab工具箱。
This Toolbox provides a number of functions that are useful in computer vision,
machine vision and related areas. It is a somewhat eclectic collection reflecting
the author s personal interest in areas of photometry, photogrammetry, colorimetry. It
covers functions such as image file Reading and writing, filtering, segmentation,
feature extraction, camera calibration, camera exterior orientation, display,
color space conversion and blackbody radiators. The Toolbox, combined
with MATLAB and a modern workstation computer, is a useful and convenient
environment for investigation of machine vision algorithms. It is possible to use
MEX files to interface with image acquisition hardware ranging from simple
framegrabbers to Datacube servers.
