  • Processor and method for writeback buffer reuse
    Patent number: 8145848
    Abstract: A processor may include a writeback configured to perform a first writeback operation to store corresponding writeback data back to a lower-level memory upon eviction of the writeback data, and a writeback buffer configured to store the writeback data after the writeback data has been evicted from the writeback cache and before the writeback data has been sent to the lower-level memory. After the writeback data has been sent from the writeback buffer to the lower-level memory, and before the lower-level memory has acknowledged completion of the first writeback operation, the writeback cache may perform a second writeback operation to store different writeback data in the writeback buffer in response to eviction of the different writeback data, such that a total size of the writeback data for the concurrently outstanding writeback operations exceeds a total size of writeback data that the writeback buffer is capable of concurrently storing.
