因为加入输入为4位信号,如果SUM_WIDTH要用clog2之后不加1的话,SUM_WIDTH的位宽为2bit,最大表达为11(3),而4位信号全为1时,sum应该为4,表达位宽不够。 这段code综合出来的电路是什么样的呢? 很明显,这样的电路可以达到设计的目的,但是并不是最优的,大家可以计算一下每个2bit full adder需要多少门,compara...
A CAS block is made up of an n-bit comparator, two n-bit multiplexers to select from inputs A and B where n-bit is the data width of A and B. There can be two configurations of the CAS block to sort the numbers in an ascending or descending order....

Do I need the additional comparator ? I just wanna write my case code simply with for loop statement, without additional mux, adder or etc. いいね!返信prathikm (Member) User1632152476299482873 によって 2021年9月25日(15:20) に編集されました*...
