11 Questions
What is the main purpose of cache memory?
To provide a fast, small memory that holds copies of frequently accessed main memory locations
What is the relationship between cache memory and main memory?
Cache memory is a copy of a portion of main memory
How does cache memory exploit the principle of locality?
By storing a copy of a portion of main memory that is likely to be accessed in the near future
What is the relationship between cache memory and processor execution?
Processor execution is limited by main memory cycle time
What is the role of secondary memory in the memory hierarchy?
Secondary memory is used to store program and data files
What is the primary purpose of interrupts in a processor?
To improve processor utilization by allowing it to handle other tasks while waiting for slower devices
How does a processor handle multiple interrupts occurring simultaneously?
It uses a priority scheme to determine which interrupt to handle first
What is the relationship between memory access speed and cost per bit in the memory hierarchy?
Faster access time means greater cost per bit
What is the hit ratio in the context of a two-level memory system?
The fraction of memory accesses that are found in the faster memory level
What is the principle of locality in the context of memory references?
Memory references by the processor tend to cluster in specific regions of memory
What is the relationship between memory capacity and cost per bit in the memory hierarchy?
Greater capacity means smaller cost per bit
Test your knowledge on interrupts and their role in the processor sequencing. This quiz covers common classes of interrupts, flow of control without interrupts, interrupt processing, and transfer of control via interrupts.
