IP核（Intellectual Property core，知识产权核）是一段具有特定电路功能的硬件描述语言程序，可移植到不同的半导体工艺中生产集成电路芯片。IP核设计电子系统引用方便、修改容易。本书用轻松的语言和实例讲解方式，介绍了ASIC前端/FPGA设计的有关知识，包括ASIC、IP核系统设计选择；设计时重点关注和系统架构设计的一般理念与关键思想，如Verilog语言的可综合性、时钟系统概念、设计流程等；用Verilog语言描述简单单元的设计；介绍数学运算与信号处理单元设计与结构优化。
本书尽量剥离了很多信号处理的理论知识，本书注重于系统结构以及结构优化的介绍，符合工程师的阅读需要。本书语言风趣，通俗易懂，配有一定插图，方面读者阅读理解。

Content Description

数字逻辑设计的精妙之处，在于根据不同的系统需求获得功能相同但结构完全不同的系统架构，这也是所谓“面积与速度”的平衡问题。本书运用幽默轻松的语言方式，介绍各种IP核在不同要求下的实现方法，潜移默化地传递了数字逻辑系统的设计思想。由于大部分工程师对于信号处理等知识的把握不是特别理想，所以本书剥离了理论知识的传统讲解方式，注重系统结构以及结构优化的介绍，以适应此类工程师的需要。__eol__第1章介绍了数字逻辑设计的基础概念，这些是设计的基础。只有把握这些内容，才能够真正进行合格的FPGA或者ASIC前端设计。第2～5章，由浅入深详述了从简单的选择器到复杂的快速傅里叶变换的一系列IP核内部结构，包含IP核多种可能的结构，方便读者根据不同的系统需求选择使用。第6章举例介绍了复杂系统设计所需要考虑的各种问题，使读者体会到“面积与速度”均衡的思想。

Author Description

吴涛，通信专业博士，从事过关于W-CDMA的FPGA IP core设计工作，也完成过W-CDMA和TDS-CDMA的接收机理论研究和链路仿真，及无线通信的系统设计和标准设计工作。目前，有100多个已经授权的发明专利，也是某个通信行业标准文件的第一作者，还有专利的思想被写入3GPP的协议。作者在某电子信类专业论坛上享有一定知名度，以文风幽默，谈古论今，故事性讲解擅长。

Book Abstract

《IP核芯志：数字逻辑设计思想》：
（1）通用性，即具有某一功能的IP核，可以在不同应用方面使用。IP核具有满足子功能可配置甚至可编程的特点，如最常见的嵌入式CPU模块具有非常好的通用性。
（2）正确性，即有百分之百的保证。IP核的实现严格遵守一系列的可重用设计开发规范，IP核的验证用例必须具有完备性，功能覆盖率、测试覆盖率都能达到百分之百。IP核工作的临界条件提供相应的大流量测试、随机性测试，甚至能够提供软硬件协同仿真的测试环境等。
（3）可移植性，即IP核的实现，如行为描述、网表、GDSII文件，具有可移植性，其设计输入可以在不同的开发平台上重现；综合用批处理文件具有可移植性，IP核的综合结果可以用不同的综合工具，在不同的综合库条件下正确重现；IP核的验证可以用不同的仿真器，在不同的仿真库条件下重现。（说句他们不喜欢听的，这个可移植，一般最多是一个厂家的不同器件之间的移植。A公司不会“仁”到这种程度：为作为竞争对手的B公司，去做免费IP核。这个就是唐诗里的“却为人做嫁衣裳”的行为，只有大脑有些贵恙的人才玩。这是商场，不是“失弓得弓”那么简单的事情。）
至于这些优点里面是否有水分和掺了几成水，列位自己琢磨。
3.维谷，又见维谷
现在，大家来尝试着讨论一下，“一个项目里面是否该采用IP核，以及该采用多少？”这个问题。
IP核的概念和优点，前面说了很多了。接下来该发挥贫僧嘴贱的特点了，聊聊IP核的坏处和问题。
首先，一般稳定的，特别是可以供ASIC设计的，IP核是要花钱的。这有点废话的感觉，自己开发也要花人力资源和实践，这对老板而言也是钱。但是，很多IP核要持续花钱。也就是说，你用一次就要交一次钱。这个是固定成本。相对而言，自己开发则是一次性投资，后期会被出货量平均掉。这个不是一般开发工程师的事情，大伙儿看看热闹好了，不必追究细节。
其次，采用IP核的系统结构，就必须符合这些IP核的结构，不利于结构的优化。本书的后面，大家将会看到：好的结构，需要把单元的界限打破，重新组合。用了IP核，这种重新组合的限制就很大了。
最后，用IP核会损伤一些工程师的自尊心，还会造成一些人不求甚解的倾向。这个又是管理的事情，我们不关心。说一个故事吧，在《市场学》里面常作为案例。
