Programmable error actions for a cache in a data processing system |
摘要 |
A data processing system and method of operation has a processor coupled to a cache. Cache control circuitry is coupled to the cache and performs error detection. A user programmable error action control register stores a control value for selecting a type of error action to be taken when a cache error is detected. A first value of the control value permits handling of a cache error that is transparent to the processor, and a second value permits handling of the cache error by taking an exception that is visible to the processor. Various alternate actions to a detected error, including error correction or cache line invalidation, may be taken in response to other values of the control value. |
