This is a mutlicore and cluster(of single-core,multi-core systems) matrix inversion code. Which uses the MPI(Message Passing Interface) for communication across the compute nodes of cluster and using thread-API based OpenMP(Open Multi Processing) between cores of intra-compute or head node.

演示中使用的數據庫為省、市、縣三級數據庫 演示程序實現了省、市、縣三級聯動（ajax技術） 程序調用方法： 1：把 <script language="javascript" src="js/jquery.js"></script> <script language="javascript" src="js/firste_city.js"></script> 貼到網頁<head></head>之間 2：把 <span id="f"></span><span id="floading"></span><span id="ferr"></span> 貼到需要顯示省、市、縣下拉列表的地方 程序中使用了jquery庫，感謝其作者John Resig。

This tutorial explains how to communicate with IO devices on the DE2 Board and how to deal with interrupts using C and the Altera Monitor Program. Two example programs are given that diplay the state of the toggle switches on the red LEDs. The fi rst program uses the programmed I/O approach and the second program uses interrupts.

This application report discusses the design of non-invasive optical plethysmography also called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). The pulsoximeter consists of a peripheral probe combined with the MCU displaying the oxygen saturation and pulse rate on a LCD glass. The same sensor is used for both heart-rate detection and pulsoximetering in this application. The probe is placed on a peripheral point of the body such as a finger tip, ear lobe or the nose. The probe includes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) and the other in the infrared spectrum (940nm). The percentage of oxygen in the body is worked by measuring the intensity from each frequency of light after it transmits through the body and then calculating the ratio between these two intensities.

To write data to the FIFO, present the data to be written and assert the write enable. At the next rising edge of the clock, the data will be written. For every rising edge of the clock that the write enable is asserted, a piece of data is written into the FIFO. If the FIFO has data in it, the value at the head of the FIFO is present on the FIFO data output. To read data from the FIFO, assert the read enable. At the next rising edge of the clock, capture the data output the FIFO will subsequently advance to the next piece of data stored in the FIFO.
