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:

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:

1. Stage D: Generates eight partial products. This stage is the initial step where the multiplicand and multiplier are combined to produce partial products.
2. Stage C: Consists of two levels of four CSAS (Carry Save Adders). This stage processes the partial products to reduce the number of operands.
3. Stage A: Consists of two CSAS and it merges four numbers from the previous stage. This further reduces the operands.
4. 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.
