在ise10.1.3 Xilinx PicoBlaze的应用开发。

两个例子提醒我们如果我们要使用锁存器则不需要任何操作，如果我们想避免锁存器的话，我们要让这个元器件的每一个可能条件赋予一个值-signal or variable "" may not be assigned a new value in every possible path through the Process Statement

第十一章到第十三章的代码 本书通过100多个模块实例，详细地讲解了Verilog HDL程序设计语言，全书共分13章，内容涉及VerilogHDL语言基本概念、建模、同步设计、异步设计、功能验证等，实例包括各种加法器/计数器、乘法器/除法器、编码器/译码器、状态机、SPIMaster Controller、I2C Master controller、CAN ProtocolController、Memory模块、JPEG图像压缩模块、加密模块、ATA控制器、8位RISC-CPU等及各个实例模块相应的Testbench，所举实例具有很强的实用性和代表性，每个实例均给出了介绍、功能分析、程序代码和结果演示。(Chapter XI to the 13th chapter of the code in this book through more than 100 module instance, explain in detail the Verilog HDL programming language, the book is divided into 13 chapters, covering basic concepts VerilogHDL languages, modeling, synchronous design, asynchronous design, functional verification, etc. Examples include a variety of adder/counter, multiplier/divider, encoders/decoders, state machines, SPIMaster Controller, I2C Master controller, CAN ProtocolController, Memory modules, JPEG image compression module, encryption module, ATA controller, 8-bit RISC-CPU, etc. and the various instances of the corresponding module Testbench, The examples are highly practical and representation, each instance of it all gives the introduction, functional analysis, program code and results presentation.)

说明：  用verilog语言实现计算反正切函数，在软件无线电中解调PM/FM中使用的尤为频繁。上传的压缩包是modelsim工程，基于6.5c,里边包含一个完整的PM波产生以及解调过程的matlab文件仿真，并取其中间的I和Q支路做为verilog文件的输入，并将其借条输出与MATLAB实际解调输出作比较。 鉴相器的设计基于CORDIC算法，其精度取决于迭代的深度。由于工程实际运用只需要解调出atan值，并不需要绝对的值，所以并没有给予加权，需要的同学可以自己加上。(Calculated using verilog language arc tangent function, the software radio demodulation PM/FM is particularly used frequently. From the archive is modelsim project, based on 6.5c, inside the PM contains a complete demodulation process of wave generation and simulation matlab file, and whichever is the middle of the I and Q branch verilog file as input, and its IOU demodulated output and actual output of MATLAB for comparison. Phase detector design is based on CORDIC algorithm, its accuracy depends on the iteration depth. As the practical application of engineering demodulated atan value only and does not need absolute value, and there is no weight given to the need of the students can add their own.)
