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.
