介绍专用集成电路设计的一本书，很有参考价值，适合高年级本科生和研究生(Introduction ASIC design a book, a good reference for senior undergraduate and postgraduate)

说明：  本书采用大量图片，通过详细的分步讲解，以直观、易懂的方式展现了7个数据结构和26个基础算法的基本原理。第1章介绍了链表、数组、栈等7个数据结构；从第2章到第7章，分别介绍了和排序、查找、图论、安全、聚类等相关的26个基础算法，内容涉及冒泡排序、二分查找、广度优先搜索、哈希函数、迪菲 - 赫尔曼密钥交换、k-means 算法等。 本书没有枯燥的理论和复杂的公式，而是通过大量的步骤图帮助读者加深对数据结构原理和算法执行过程的理解，便于学习和记忆。将本书作为算法入门的第一步，是非常不错的选择。(This book uses a large number of pictures, through detailed step-by-step explanation, in an intuitive and easy to understand way to show the basic principles of 7 data structures and 26 basic algorithms. Chapter 1 introduces seven data structures such as linked list, array and stack; from Chapter 2 to Chapter 7, 26 basic algorithms related to sorting, searching, graph theory, security and clustering are introduced respectively, including bubble sorting, binary searching, breadth first search, hash function, Diffie Herman key exchange, K-means algorithm, etc. This book does not have boring theory and complex formula, but through a large number of step diagrams to help readers deepen the understanding of data structure principle and algorithm execution process, easy to learn and remember. This book as the first step of the algorithm, is a very good choice.)
