Question

 

You have a CPU which contains two processor cores, connected via a bus. Each core has its own 8 row, direct-mapped L1 cache and the two caches are coherent via snoopy cache coherent over the bus, with a write-invalidate mechanism. The block size in the cache is 8 bytes (two words).

Core A: Load byte address 63

Core A: Load byte address 57

Core B: Store byte address 63

Core A: Store byte address 63

Core B: Load byte address 102

Core A: Load byte address 121

Core A: Load byte address 57

 

 

For each access from the list above, please indicate whether the access would be a hit, a compulsory miss, a conflict miss, a capacity miss, or a coherence miss. Before the sequence begins, both caches are empty.

 

 

First access (Core A address 63):

 

Second access (Core A address 57):

 

Third access (Core B address 63):

 

Fourth access (Core A address 63):

 

Fifth access (Core B address 102):

 

Sixth access (Core A address 121):

 

Seventh access (Core A address 57):
