Consdier a main memory with 32-bit addresses, access time of 100 clock cycles, and a cache in the memory hierarchy as described in the table below. a) If the block size is increased, can you please discuss (non-quantitatively) how the miss rate and miss penalty would change (i.e., increase, decrease, or it depends) for this direct-mapped cache? Please discuss and justify your answer.

Question

Consdier a main memory with 32-bit addresses, access time of 100 clock cycles, and a cache in the memory hierarchy as described in the table below.

a) If the block size is increased, can you please discuss (non-quantitatively) how the miss rate and miss penalty would change (i.e., increase, decrease, or it depends) for this direct-mapped cache? Please discuss and justify your answer.

 

The table provides information related to a computer cache system: - **Cache Size:** 32K Bytes - **Block Size:** 4 Bytes (1 word) - **Cache Type:** Direct-Mapped - **Hit Time:** 1 cycle - **Miss Rate:** 5% The table has placeholders for the following calculations: - **Number of bits in Tag** - **Number of bits in Index** - **Number of bits in Offset** These values are essential for understanding how the cache is addressed and how efficiently it operates. Students are encouraged to calculate these values using the given parameters for cache size and block size.
