Memory Wall
- Computer Systems
- Processor speed increased by 55% every year.
- $\log(2) \over \log(1.55)$ gives $1.58$, aligning with the Moore's Law.
- Memory speed increased by 7% every year.
- Latency gets higher and higher between the processor and memory
- Solution with Latency and Throughput
- Improve Latency
- Improve the speed of memory itself (hard!)
- Put memory closer to the processor or within the processor.
- Improve Throughput
- Organize more efficiently
- Hierarchy of Memories
- Principles of Locality
- Improve Latency
