《FPGA实现算术函数指南》是一本专为FPGA用户和IP核心设计者编写的实用性书籍，旨在帮助他们开发新的、特定的组件，以提高执行效率并扩展其功能库。本书的核心焦点在于电路合成，它详细介绍了如何将执行复杂函数的算法转化为可综合的电路描述，以及设计师在优化电路成本、延迟或功耗方面可以做出的最佳选择。不同于算法理论书籍，这本书着重于算法到硬件的高效转换，通过诸如并行处理、流水线技术、循环展开等技术手段。 作者们，Jean-Pierre Deschamps、Gustavo D. Sutter和Enrique Cantó，分别来自西班牙的罗维拉-维吉里大学和马德里自治大学的计算机工程学校，他们共同分享了丰富的FPGA实施经验。书中提供了大量的实例，涵盖了各种算术函数的FPGA实现，所有的电路设计都是基于VHDL模型，并且附带完整的、可以直接进行综合的源代码下载，方便读者实际操作和学习。 本书的出版遵循Springer的" LectureNotes in Electrical Engineering"系列，读者可以通过Springer官网获取更多相关卷信息。此外，版权方面，该作品受到法律保护，未经许可，禁止任何形式的翻译、重印、复制、广播、微缩胶片复制或任何形式的信息存储和检索。此书的国际标准书号(ISBN)和电子书号(e-ISBN)以及DOI（数字对象标识符）也一应俱全，体现了Springer作为科学与商业媒体在学术出版领域的权威性。 《FPGA实现算术函数指南》是一本实用的工具书，对于希望深入了解FPGA硬件实现和算法优化的工程师来说，它不仅提供了理论指导，还提供了丰富的实战案例和资源，有助于提升读者在FPGA设计中的实践能力。无论是初学者还是经验丰富的从业者，都能从中受益匪浅。

FPGA Implementation of Sine and Cosine Generators Using the CORDIC Algorithm

2013-03-24 上传
Tanya Vladimirova and Hans Tiggeler Surrey Space Centre University of Surrey, Guildford, Surrey, GU2 5XH Tel: +44(0) 1483 879278 Fax: +44(0) 1483 876021 Abstract: This paper is concerned with FPGA implementation of CORDIC schemes for fast and silicon area efficient computation of the sine and cosine functions. The results of theoretical investigation into redundant CORDIC are presented. Summary of CORDIC synthesis results based on Actel and XILINX FPGAs is given. Finally applications of CORDIC sine and cosine generators in small satellites are discussed. Keywords: CORDIC, sine, cosine, FPGA, synthesis, redundant signed-digit system.

Use C programe: Add the code in the function int stringCombine which adds the string stored in src to the end of dest. The header file string.h CANNOT be included. Assume that the length of the combined string is below 256. The main function is as follows: # include <stdio.h> void stringCombine(char* dest, char* src); int main() { char str1[100], str2[256]; gets(str1); gets(str2); stringCombine(str2, str1); puts(str2); return 0; } void stringCombine(char *dest, char *src){ //Your code here. }

[warning] pointer to a function used in arithmetic [-wpointer-arith]

2023-06-28 上传
[warning] pointer to a function used in arithmetic [-wpointer-arith] 的意思是“指向函数的指针用于算术运算时发出警告”。这个警告通常是由于在对指向函数的指针进行算术运算时，编译器无法确定运算的结果，...

Little Gyro has just found an empty integer set A in his right pocket, and an empty integer set B in his left pocket. At the same time, Little Gyro has already thought about two integers n, m in his mind. As Little Gyro is bored, he decides to play with these two sets. Then, Little Gyro is ready to divide the integer series 1,2,3...m−1,m to these two empty sets. With the following rules: If the number is an integer multiple of n, Little Gyro will put it in set A. Otherwise, Little Gyro will put it in set B instead. Now given two integers n, m, after these operations, Little Gyro wants to know the result of sum(B)−sum(A) and ask you for help, please help him to calculate. Input Specification: There are multiple test cases. The first line of the input contains an integer T (1 ≤ T ≤ 10 5 ), indicating the number of test cases. For each test case: Each line contains two integers n, m (1 ≤ n, m ≤ 10 9 ), indicating the length of the sequence. Output Specification: For each test case output an integer indicating the result of sum(B)−sum(A). Sample Input: 3 3 5 2 10 3 16 Sample Output: 9 -5 46 Hint: For the first sample, after these operations, A = <3>, B = <1,2,4,5>, and the answer is 9. For the second sample, after these operations, A = <2,4,6,8,10>, B = <1,3,5,7,9>, and the answer is -5.

To solve this problem, we can first calculate the sum of integers in set A and the sum of integers in set B separately. The sum of integers in set A is the sum of all integer multiples of n within ...
