ARM EN0-001 Question Answer

During an investigation into a software performance problem an engineer doubles the clock frequency of a cached ARM processor running the software. Unfortunately the performance of the application does not increase by very much, despite running on the processor for 100% of the time. What is likely to be the main bottleneck in the system?

The processor is context switching between multiple processes

Performance is limited by the speed of external memory

The processor is taking too long to execute branch instructions

The system is raising interrupts too fast for the processor to handle them
