VIRTUAL UNIFIED INSTRUCTION AND DATA CACHES |
| 摘要 |
Execution of a store instruction to modify an instruction at a memory location identified by a memory address is requested. A cache controller stores the memory address and the modified data in an associative memory coupled to a data cache and an instruction cache. In addition, the modified data is stored in a second level cache without invalidating the memory location associated with the instruction cache. |
