  • 7段數碼顯示譯碼器設計7段數碼是純組合電路

    7段數碼顯示譯碼器設計7段數碼是純組合電路,通常的小規模專用IC,如74或4000系列的器件只能作十進制BCD碼譯碼,然而數字系統中的數據處理和運算都是二進制的,所以輸出表達都是十六進制的,為了滿足十六進制數的譯碼顯示,最方便的方法就是利用譯碼程序在FPGA/CPLD中來實現。例子作為七段譯碼器,輸出信號LED7S的7位分別接數碼管的7個段,高位在左,低位在右。例如當LED7S輸出為“1101101”時,數碼管的7個段g、f、e、d、c、b、a分別接1、1、0、1、1、0、1;接有高電平的段發亮,于是數碼管顯示“5”。

  • The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produce

    The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.

  • This document provides guidelines and describes how to easily port S60 2nd Edition C++ application

    This document provides guidelines and describes how to easily port S60 2nd Edition C++ applications to S60 3rd Edition. The document has been written based on experiences of porting regular S60 2nd Edition applications, such as the S60 Platform: POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from the example are shown in Chapter 8, “Application build changes,” and in Appendix A, “Code example." In addition, Appendix B, "Commonly used functions that require capabilities," and Appendix C, "Commonly used interfaces that have been changed or removed," provide useful information on some frequently used functions and interfaces in third-party applications.
