Consider a pipeline unit for fixed - point multiplication of 8-bit integers. Arrange the following stages in a correct sequence.
Stage A : Consists of two CSAS and it merges four numbers from previous stage.
Stage B : is a CPA, which adds up the two numbers
Stage C : is made upto two level of four CSAS.
Stage D : Generates eight partial products.
Choose the correct answer from the options given below:
1.C, A, B, D
2.D, C, A, B✓ Correct
3.B, D, C, A
4.A, C, D, B
Solution
The correct answer is Option 2: D, C, A, B
Explanation:
The correct sequence of stages for fixed-point multiplication of 8-bit integers is as follows:
Stage D: Generates eight partial products. This stage is the initial step where the multiplicand and multiplier are combined to produce partial products.
Stage C: Consists of two levels of four CSAS (Carry Save Adders). This stage processes the partial products to reduce the number of operands.
Stage A: Consists of two CSAS and it merges four numbers from the previous stage. This further reduces the operands.
Stage B: Is a CPA (Carry Propagate Adder), which adds up the two numbers. This final stage produces the final product by adding the last two numbers.
