位运算

One should also remember the higher productivity of 64-bit versions of programs which is caused by a greater number of registers, extended abilities of floating point arithmetic and the possibility of working with 64-bit numbers.

人们应该还记得64更高的生产率，这些是由更多的寄存器位版本的程序造成的，扩大了浮点运算能力，与64位数字的工作的可能性。

Based on a new modified Wallace multiplier structure, named bi-forked Wallace multiplier structure, this paper presents the design of a highly re-configurable Multiplier for VLIW multimedia-processor. We found a reusable design method to extend multiplier with full adder array. The Structure can enable 32/16/8 bit operands, and has been optimized for speed and area.

在VLIW多媒体芯片的设计过程中，针对传统乘法器与加法器的不足，提出了一种新的分叉华莱氏树结构的乘法器模型，采用可重用的模块化设计思想，通过重用一位全加器阵列对乘法器进行扩展，处理器可以在一个乘法器单元内部同时支持多个32/16/8位的乘法运算，同时使乘法单元的速度和面积均得以优化。

Downward continuation is an important operation in potential field data processing and inversion, but its instability problem influences its application in many processing and inversion techniques.

位场向下延拓是位场数据处理和反演中的重要运算，但是它的不稳定性影响了它在许多处理和反演方法技术中的应用。

The author mainly realized the method of generating the large random numbers and judging the prime number using Lehmann means,then three pairs of secure key with different lengths (256 bits,512 bits,1024 bits) was generated to meet the demand of different security grade. In encryption module,modular multiplication arithmetic of large number was realized adopting addition chaining. In decryption module,extended Euclid was used to get inverse,and the Chinese remainder theorem was used to realize decryption,which increased the speed of decryption greatly.

作者主要实现了大随机数的生成、采用整除小素数和勒曼测试法判定素数，可以生成三种不同长度的密钥对(256位、512位、1024位)来满足不同的加密安全等级的需求；加密模块中，选用了二进制序列的乘法方法，实现了大数模幂乘运算；解密模块中，引用了扩展的欧几里德法求逆元，并采用中国剩余定理实现解密过程，大大提高了解密速度。

One or more digits,produced in connection with an arithmetic operation on one digit place of two or more numeral s in positional notation,that are forwarded to another digit place for processing there.

以按位记数法表示的两个或多个数在一个数字位上进行算术运算所产生的一位或多位数，该数被传送到另一个位上以进行处理。

One or more digit s,produced in connection with an arithmetic operation on one digit place of two or more numerals in positional notation,that are forwarded to another digit place for processing there.

以按位记数法表示的两个或多个数在一个数字位上进行算术运算所产生的一位或多位数，该数被传送到另一个位上以进行处理。

In computing , most significant bit is the bit position in a binary number having the greatest value. The msb is sometimes referred to as the left-most bit , due to the convention in positional notation of writing more significant digits further to the left.

在计算机运算中，最高有效位，是指在一个二进制数中具有最大值的那一个二进制位。msb有时也被称为"最左边的位"，这是因为在权位记数法中习惯上将较大的有效数字顺序的写在左边。

A good use of the integer type, the biggest 9999990 to support the decimal integer, It can perform large integers, plus or minus, multiplication, addition and modular, with a big round of the largest factions, extended Euclidean algorithm, the Chinese remainder theorem algorithm, Miller - Rabin primality testing algorithm, random generation of arbitrary integer spaces such as libraries, This kind of dynamic library has been used for commercial software, the reliability and speed is affirmed.

一个很好用的大整数的类，最大可支持9999990位的十进制整数，可进行大整数的加、减、乘、除和取模运算，并带有求大整数的最大公因数、扩展Euclidean算法、中国剩余定理算法、Miller-Rabin素性测试算法、随机生成任意位的大整数等函数库，这个类的动态库曾用于商业软件之中，其可靠性和速度是得到确认的。

The design of the ALU and the way to deal with overflow,carry-out,borrow-out, comparison of the arithmetic operations of signed and unsigned numbers are discussed here.

重点讨论了其中的32住先行进位ALU的设计，以及对补码数与无符号数算术运算的溢出、进位、借位、比较等问题的处理方法。

Modified trinary number has already taken a significant role towards carry and borrow free arithmetic operations.

修正型三进制在无需进位和借位的算术运算中有着特殊意义。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
