Description: 流水线结构是在逻辑很复杂的情况下使用,通过分栈,把一个复杂的逻辑分成若干个比较简单的块实现,减少信号的逻辑级,提高频率。最形象的实例就是位宽较大的加法器。此程序就是verilog的实现
-In the pipeline structure is complex logic case, through the sub-stack, the complex logic into a plurality of blocks of a relatively simple implementation, the logic level signal decrease, increase frequency. The most vivid example is the bit width larger adder. This program is the realization of verilog Platform: |
