One of the most misunderstood constructs in the Verilog language is the nonblockingassignment. Even very experienced Verilog designers do n...
FPGAs have changed dramatically since Xilinx first introduced them just 15 years ago. In thepast, FPGA were primarily used for prototyping ...
Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis too...
针对传统集成电路(ASIC)功能固定、升级困难等缺点,利用FPGA实现了扩频通信芯片STEL-2000A的核心功能。使用ISE提供的DDS IP核实现NCO模块,在下变频模块调用了硬核乘法器并引入CIC滤波器进行低通滤波,给出了DQPSK解调的原理和实现方法,推导出一种简便的引入?仔/4固定相移的实...
