Verilog中的移位操作有两种:逻辑移位操作(logical)、算数移位操作(arithmetic)。逻辑移位使用“<<”、和“>>”,而算术移位使用“<<<”、和“>>>”,描述以及代码示例如下所示: //本示例使用逻辑、算术右移为例: //逻辑右移(>>), 初始值为4'b1000, 移位结果为4'b0010 module shift(); reg [3:0] valu...
nonblocking assignments -> sequential blocks -> use '<=' (just think about AND gate connected with a DFF) 3. Behavioral Verilog means no specific hardware design (but should be able to envision it.) 4.Learn to use the function to calculate some value in the compiler process B. The synta...

storage devices, communication I/O, and most importantly, to the FPGA logic of the chip. On the FPGA side, we can implement VHDL/Verilog accelerators to speed-up intensive algorithms. Hence, the FPGA SoC allows for flexible and scalable designs with reducedpower dissipationand increased performanc...
This project implements a small stack computer tailored to executing Forth based on theJ1CPU. The processor has been rewritten inVHDLfromVerilog, and extended slightly. The goals of the project are as follows: Create a working version ofJ1processor (called the H2). ...

Verilog, and VHDL, formats supporting register level description languages like RTL, and formats supporting geometry description languages such as GDSII, GDSIII, GDSIV, CIF, MEBES and any other suitable formats and languages. Computer-readable media in which such formatted data and/or instructions ma...
the signal is modulated by the method of frequency shift keying. The modulation signal is composed of 4 MOS tubes of H bridge, and then through the design of the full digital phase-locked loop for demodulation. This paper presents the full digital phase-locked loop design using Verilog and ...
