7.2.1 Combinational and sequential logic In digital electronics digital outputs are generated from digital inputs. If the output of the logic circuit depends only on the present input values, we refer to the system as not having memory. Systems without memory are also known as combinational logic...
Digital electronics is the basis of modern technological advancements. Digital devices are created using the principles of Boolean logic. Boolean logic, based on the nature of the outputs, is separated into combinational logic and sequential logic. Each type of logic can be used to implement differe...
可以根据内部是否有存储状态划分成: Combinational Logic(无存储状态,纯计算单元) Sequential Logic (有存储状态,可以认为比如寄存器之类的) 布尔代数 熟悉布尔代数在设计逻辑电路的时候可以帮助我们更好的思考。一些常用的公里和定律,不列举了。不同的布尔表达式虽然在输出结果上是一致的,但是会映射到不同的逻辑门实现上...

Combinational Logic 组合逻辑电路(CL) 用来执行一些功能,类似函数 比如两个数的加法电路(ALU算术逻辑单元) Sequential Logic 时序逻辑电路(SL) 用来记忆或储存信息的电路 比如内存和寄存器 逻辑门 可以记住,AND因为有一个D,所以电路符号长得就像D,然后小圆圈代表Not, ...

designers simplify the complex logic and rewrite it as an “if” statement on the register assignment, thereby simplifying the job of RTL synthesis tools. However, identifying sequential clock gating opportunities is beyond the scope of RTL synthesis tools. Power conscious designers try to analyze th...
