ECE345, Visual-to-Audio Electronic Travel Aid Code for TM320C54x (v2a.asm) download This project involves the design and implementation of a audio synthesis device that converts moving images into audio signals. The system is built on a TM320C54x DSP with interface to an IMAQ camera module via the serial port on a PC. Brief description: A LabVIEW VI acquires an image from the IMAQ camera module. It quantizes the image into a 5x5, 3-bit image, and sends the data to the TM320C54x DSP via a serial port. The TM320C54x DSP constructs a 64-tap FIR by combining a series of 64-tap head related transfer functions (HRTF) according to the incoming data, and then filters an input audio signal with this FIR filter, in effect creating a correspondence between the filtered signal and the original image.

C51源程序集锦 This a demo program showing a way to perform simultaneous RS-232 transmit and receive using only one hardware timer. The transmit and receive routines divide each bit time into 4 slices to allow synchronizing to incoming data that may be out of synch with outgoing data.

利用java实现文件的AES加密功能 This Java AES Crypt package contains the Java class es.vocali.util.AESCrypt, which provides file encryption and decryption using aescrypt file format. Requirements The Java AES Crypt package only works in Java 6, but can be easily adapted to Java 5 by replacing the call to NetworkInterface.getHardwareAddress() with something else. In order to use 256 bit AES keys, you must download and install "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" from http://java.sun.com/javase/downloads/index.jsp

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.

Introduction Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.
