Across
  1. 2. type of buffer register.
  2. 4. page replacement algorithm.
  3. 5. Replacement Algorithm/It must decide which page in main memory ought to be removed to make a new room for a new page.
  4. 7. small unit of physical memory space.
  5. 8. Code/Single bit error correction method.
  6. 12. Mapping/Each word of cache can store 2 or more words of memory under the same index address.
  7. 13. penalty/Additional cycles required to serve the miss.
  8. 14. Cache/Secondary cache in multilevel cache architecture.
  9. 15. cache like quick reference for page table.
  10. 17. Hit/A referenced item is found in the cache by the processor.
  11. 18. locality/Items whose addresses are near one another tend to be referenced close together in time.
Down
  1. 1. type of RAM that consists of circuits that are capable of retaining their state as long as the power is applied.
  2. 3. Memory/Permits the user to construct programs as though a large memory space were available.
  3. 5. of locality/We can predict with reasonable accuracy what instructions and data a program will use in the near future based on its accesses in the recent past.
  4. 6. to retrieve the first word of the block.
  5. 9. Mapping/Any block location in cache can store any block in memory.
  6. 10. Back/Memory is not up-to-date, i.e., the same item in cache and memory may have different value.
  7. 11. Address Map/An address map indicating memory component and address bus representation.
  8. 16. Recently Used/Replace that block in the set that has been in the cache longest with no reference to it.
