Fixed Arithmetic pipelines
We obtain the example of multiplication of fixed numbers. The Two fixed-point numbers are added by the ALU using shift and add operations. This sequential implementation makes the multiplication a slow process. If we seem at the multiplication process cautiously, then we examine that this is the process of adding the multiple copies of shifted multiplicands as given below:
Now, we can signify the following phases for the pipeline:
These phases have been implemented using CSA tree as shown in Figure:-
Arithmetic pipeline for Multiplication of two 6-digit fixed numbers
Bubbling the Pipeline: Bubbling the pipeline (also known as a pipeline break or pipeline stall) is a technique for preventing, structural, data and branch hazards from taking p
Convert (177.25) 10 to octal Ans. 177.25) 10 = ( ) 8 Firstly we take integer part Hence (177) 10 = (261) 8 Now as 0.25 x 8 = 2.00 and 0.00 x 8 = 0 Therefor
For JK flipflop J = 0, K=1, the output after clock pulse will be ? Ans. J=0 and K=1, such inputs will reset the flip-flop, after the clock pulse. Therefore whatever be the earlie
Q Consider the following expression. Assume that complement inputs are available. F(A,B,C,D) = ∑m (1,2,6,9,10,14) + ∑d (4,7,8,11,12) a. Find minimal expression for SOP. Draw
