关于FPGA流水线设计的论文 This work investigates the use of very deep pipelines for implementing circuits in FPGAs, where each pipeline stage is limited to a single FPGA logic element (LE). The architecture and VHDL design of a parameterized integer array multiplier is presented and also an IEEE 754 compliant 32-bit floating-point multiplier. We show how to write VHDL cells that implement such approach, and how the array multiplier architecture was adapted. Synthesis and simulation were performed for Altera Apex20KE devices, although the VHDL code should be portable to other devices. For this family, a 16 bit integer multiplier achieves a frequency of 266MHz, while the floating point unit reaches 235MHz, performing 235 MFLOPS in an FPGA. Additional cells are inserted to synchronize data, what imposes significant area penalties. This and other considerations to apply the technique in real designs are also addressed.

All 3G and GSM specifications have a 3GPP specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series as listed in the table below. They are followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series. The term "3G" means a 3GPP system using a UTRAN radio access network the term "GSM" means a 3GPP system using a GERAN radio access network. (Thus "GSM" includes GPRS and EDGE features.)

用汇编语言做的一个打字游戏。运行环境是MASN5.0。 1,用户打开软件时先出现欢迎界面,当用户输入字符’1’时,再进入打字界面 当用户按的是”ESC”键时,退出打字游戏 当用户输入不是数字”1”或者不是按的”ESC”键时,屏幕不动作,直到用户输入数字”1”或者按的”ESC”键时 2,打字字符从第二行开始显示(双数行为显示打字内容,单数行由用户输入) 打字内容:1), We will see his boat and then.We ll say goodbye to him. 2), He ll be away for two months.We are very proud of him. 3,用户输入的和上一行相对应相等时,表示输入正确,否则输入错误,则显示’#’ 当用户按下”ESC”键,退出打字程序 4,显示用户打字的正确性,假如错误数小于10字符,显示” Very Good!” 否则显示” Very Bad!” 5,当用户输入一次时,假如用户还想重新打字游戏,请按数字键”3”,否则按”ESC”键退出打字程序

Implemented BFS, DFS and A* To compile this project, use the following command: g++ -o search main.cpp Then you can run it: ./search The input is loaded from a input file in.txt Here is the format of the input file: The first line of the input file shoud contain two chars indicate the source and destination city for breadth first and depth first algorithm. The second line of input file shoud be an integer m indicate the number of connections for the map. Following m lines describe the map, each line represents to one connection in this form: dist city1 city2, which means there is a connection between city1 and city2 with the distance dist. The following input are for A* The following line contains two chars indicate the source and destination city for A* algorithm. Then there is an integer h indicate the number of heuristic. The following h lines is in the form: city dist which means the straight-line distance from the city to B is dist.

JDiff is a Javadoc doclet which generates an HTML report of all the packages, classes, constructors, methods, and fields which have been removed, added or changed in any way, including their documentation, when two APIs are compared. This is very useful for describing exactly what has changed between two releases of a product. Only the API (Application Programming Interface) of each version is compared. It does not compare what the source code does when executed.

* This a software code module for a time-of-day clock object. * The clock may be fixed 12-hour, fixed 24-hour, or dynamically * configurable between these two types. Clock data can be accessed * as a binary number representing the number of minutes since midnight * or a BCD number formatted according to the time-of-day description * in the TIME module 0404x. The functions work with time-of-day values * which conform to normally accepted clock values of 1:00 to * 12:59 BCD / 0 to 719 binary for a 12-hour clock or clock values * 00:00 to 23:59 BCD / 0 to 1439 binary for a 24-hour clock. On power-up * the clock is 12:00 BCD / 0 binary for a 12-hour or dynamically * configurable clock, or 00:00 BCD / 0 binary for a 24-hour clock.

* DEFINITION * This is the header file for a library module used to calculate the median * of a list of values. It finds the value that would be in the center if * the list were sorted. If the list contains an even number of values, the * lower of the two center values is reported. The values themselves are not * sorted or modified in any way. This algorithm can be used as a filtering * tool for rejecting noisy data.
