1. Detailed Memory Hierarchy Exploring Memory Levels, Caching, and Optimization

2. Role of Cache Memory Cache memory is used to store copies of frequently accessed data from the main memory. It improves performance by reducing the average time to access data from the main memory. There are different levels of cache: - **L1 Cache**: Fastest, located directly on the processor. - **L2 Cache**: Slower than L1 but larger. - **L3 Cache**: Shared among multiple cores, slower but larger.

3. Cache Miss Types 1. **Compulsory Misses**: Occurs when data is accessed for the first time. 2. **Capacity Misses**: Happens when the cache is too small to hold all needed data. 3. **Conflict Misses**: Occurs when multiple data locations map to the same cache location.

4. Cache Optimization Techniques 1. **Block Size Optimization**: Adjusting the size of the cache block to optimize memory access. 2. **Associative Mapping**: Improving cache lookup by allowing a data block to be stored in multiple locations. 3. **Write-through vs Write-back**: Managing how data is written to cache and main memory.
