Question

CI-E HE Gen.3 7. What is the gate delay for an unsigned 5-bit array multiplier (7 points)?

Answer 1

LET US FIRST UNDERSTAND THE BASIC TERMS RELATED TO THE QUESTION :

GATE DELAY : many of the integrated circuits works too fast and has the frequency of it so less that the duration between the input and output calculation is not possible thus we can say that the the delay is always associated with the the .reason when the system works too slowly than the delay is reduced . we all know the gate signal is thatwhich is used to turn on the thyristor and which is used to work along with.

5-BIT ARRAY MULTIPLIER : Array multiplier is well known due to its regular structure. Multiplier circuit is based on add and shift algorithm. Each partial product is generated by the multiplication of the multiplicand with one multiplier bit. The partial product are shifted according to their bit orders and then added. when it is associated with the 5 bit than it is called as the 5-bit array multiplier.

GATE DELAY OF 5 -BIT MULTIPLIER: The example of the 5-bit array multiplier can be used as follows :

in the same way by shifting and multiplying the multiplication takes place and can be used to multiply in the various ways .

the result of the  Row 1 is first taken and than they are added to the second row and with the help of this row is added to the second row and thus the product is finally obtained after adding all the rows in sequence and thus answer is obtained .

The gate delay gives the delay to the next row by a bit and thus that is added and the multiplication and the answer is obtained . We could describe this with the help of the diagram given below :

thus in this way thew multiplication takes place with the help and by providing the gate delays .
