Answer 1

The correct answer is Option 2) Floating-point operations.

Key Points

Arithmetic pipelines are specialized pipelines designed to perform complex arithmetic computations efficiently by breaking them into multiple stages.
They are especially useful for floating-point operations such as addition, subtraction, multiplication, and division.
These operations involve multiple steps (e.g., alignment, normalization, rounding) that can be pipelined to improve performance.
Each stage of the pipeline handles a part of the floating-point computation, allowing overlapping execution of multiple operations.
This enhances the throughput of floating-point arithmetic, making it ideal for scientific and engineering applications.

Additional Information

Option 1 – Incorrect: Popping a value from a stack is a simple memory operation, not arithmetic in nature.
Option 3 – Incorrect: Integer operations are generally simpler and do not typically require pipelining due to fewer computation stages.
Option 4 – Incorrect: Pushing values onto a stack is a memory access operation, unrelated to arithmetic pipelines.
Example Use Cases of Arithmetic Pipelines:
- Graphics processing
- Scientific simulations
- Signal processing
- Mathematical co-processors in CPUs
