Verilog HDL语言的快速参考指南

Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory, associative storage, or associative array, although the last term is more often used for a programming data structure.

本书简要介绍了Verilog硬件描述语言的基础知识，包括语言的基本内容和基本结构 ，以及利用该语言在各种层次上对数字系统的建模方法。书中列举了大量实例，帮助读者掌握语言本身和建模方法，对实际数字系统设计也很有帮助。本书是Verilog HDL的初级读本，适用于作为计算机、电子、电气及自控等专业相关课程的教材，也可供有关的科研人员作为参考书。(This book briefly introduces the Verilog hardware description language basics, including basic elements of language and basic structure, and the use of the language at various levels on the digital system modeling. The book lists a large number of examples to help readers master the language itself and the modeling of the actual digital system design is also helpful. Verilog HDL book is a primer for a computer, electronic, electrical and automatic control and other specialized courses related to materials, but also for the researchers as a reference.)
