Computing power is only useful when it is kept busy with a smooth flow of useful work. This is why is is often necessary to look beyond clock speed when comparing processors.

• True

• False

These are techniques built into contemporary processors, except:

• Pipelining

• Branch Prediction

• Benchmark

• Data flow analysis

A set of standard CPU-intensive, floating points and integers benchmarks are referred to as...

• SPEC benchmark

• PEC benchmark

• SEC benchmark

• SQEC benchmark

Amdahl's law illustrates the problems facing industry in the development of multi-core machines

• True

• False

Processor moves data or instructions into a conceptual pipe with all stages of the pipe processing simultaneously is the concept of____

• Branch Prediction

• Superscalar execution

• Pipelining

• Data flow analysis

Basic measure of computer performance are

• Instruction execution rate

• MIPS

• MFLOPS

Based on the Amdahl's law, if the proportion of the program that can take advantage of multiple cores only 0.5, no matter how many cores you use, the maximum speedup only 2
