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...

Based on this, a five-stage pipeline processor is designed using system verilog. In order to avoid the influence of the branch jump instruction on the execution efficiency of the processor, a prediction circuit based on the dynamic branch pre-method is added. And the data related controller is...
Verilog/SystemVerilog for Design and Synthesis is a comprehensive workshop covering the complete Verilog Hardware Description Language and the synthesizable portions of SystemVerilog, including user-defined types, enumerated types, structures, and self-verifying decision statements. The workshop integrates in...
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). ...

From Figure 12, it is clearly seen that DWT with five-level decompositions attain a good PSNR value; hence, it is designed and implemented in hardware using Verilog HDL and synthesized in Xilinx and Altera FPGAs to verify its device-level performance, based on VLSI parameters. Figure 12 Bits...
withFIG. 8, the polynomial arithmetic circuit204is preferably implemented using a linear feedback shift register. Again, the components of the circuit75are implemented using a hardware description language (HDL) such as verilog of VHDL (VHASIC (Very High Level ASIC) Hardware Description Language)....
