1. PL/0 語言介紹 ●PL/0 程序設(shè)計(jì)語言是一個(gè)較簡單的語言，它以賦值語句為基礎(chǔ)，構(gòu)造概念有順序、條件和重復(fù)（循環(huán)）三種。PL/0 有子程序概念，包括過程定義（可以嵌套）與調(diào)用且有局部變量說明。PL/0語言編譯程序采用以語法分析為核心、一遍掃描的編譯方法。詞法分析和代碼生成作為獨(dú)立的子程序供語法分析程序調(diào)用。語法分析的同時(shí)，提供了出錯(cuò)報(bào)告和出錯(cuò)恢復(fù)的功能。在源程序沒有錯(cuò)誤編譯通過的情況下，調(diào)用類PCODE解釋程序解釋執(zhí)行生成的類PCODE代碼。 ●保留字(關(guān)鍵字)：所謂保留字是指在Pascal語言中具有特定的含義。標(biāo)準(zhǔn)Pascal語言中的保留字一共有35個(gè)，Turbo Pascal語言一共有51個(gè)。下面是Pascal語言的保留字：AND，ARRAY，BEGIN，CASE，CONST，DIV，DO，DOWNTO，ELSE，END，F(xiàn)ILE，F(xiàn)OR，F(xiàn)UNTION，GOTO，IF，IN，LABEL，MOD，NIL，NOT，OF，OR，PACKED，PROCEDURE，PROGRAM，RECORD，REPEAT，SET，THEN，TO，TYPE，UNTIL，VAR，WHILE，WITH，EXPORTS，SHR，STRING，ASM，OBJECT，UNIT，CONSTRUCTOR，IMPLEMENTATION，DESTRUCTOR，USES，INHERITED，INLINE，INTERFACE，LIBRARY，XOR，SHL

關(guān)于FPGA流水線設(shè)計(jì)的論文 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.

LINEINTRGAL Line Integral in a 2D Vector Field. LINEINTRGAL(X,Y,U,V,C) computes the line integral along the lines given in cell array C. X and Y define the coordinates of a rectangular grid over which U and V are defined. X and Y must be monotonic and 2D plaid as ％ produced by MESHGRID. X, Y, U, and V must all be the same size.

Input The input consists of two lines. The first line contains two integers n and k which are the lengths of the array and the sliding window. There are n integers in the second line. Output There are two lines in the output. The first line gives the minimum values in the window at each position, from left to right, respectively. The second line gives the maximum values. Sample Input 8 3 1 3 -1 -3 5 3 6 7 Sample Output -1 -3 -3 -3 3 3 3 3 5 5 6 7

C++, although a marvelous language, isn t perfect. Matthew Wilson has been working with it for over a decade, and during that time he has found inherent limitations that require skillful workarounds. In this book, he doesn t just tell you what s wrong with C++, but offers practical techniques and tools for writing code that s more robust, flexible, efficient, and maintainable. He shows you how to tame C++ s complexity, cut through its vast array of paradigms, take back control over your code--and get far better results
