Study Notes
Computer Performance Metrics
- Instruction Per Cycle (IPC): Average number of instructions executed per clock cycle.
- Clock Rate: CPU's clock tick frequency.
- Throughput: System's work processing rate.
- Latency: Time to complete a task.
Techniques for Measuring Computer Performance
- Performance Counters: Provide detailed CPU activity information (branch prediction misses, pipeline stalls, cache misses), similar to memory performance counters.
- Profiling Tools: Software tools analyze program execution to identify performance bottlenecks.
- Benchmarking Suites: Collections of standardized benchmarks to compare system performance.
Factors Affecting Memory and Computer Performance
- Cache Memory: Small, fast memory storing frequently accessed data.
- Memory Hierarchy: Memory organized into levels with varying sizes, speeds, and costs
- Memory Interleaving: Dividing memory into banks to improve access time.
- Virtual Memory: Technique utilizing disk storage to expand physical memory capacity.
- Operating System: Software managing system resource allocation, including memory.
