CPU Performance and Architecture Quiz

Which architecture is easier to pipeline?

• CISC

• RISC

• Both CISC and RISC

• Neither CISC nor RISC

Answer explanation

RISC architecture is easier to pipeline because it uses a smaller set of simple instructions, allowing for more efficient instruction execution and better parallelism. CISC, with its complex instructions, complicates pipelining.

What is the purpose of normalized floating-point representation?

• Reducing data redundancy

• Ensuring unique representation of each value

• Supporting complex queries

• Using incorrect terminology

Answer explanation

Normalized floating-point representation ensures unique representation of each value by standardising the format, which helps avoid ambiguity and maintains precision in numerical computations.
