摘要： Cache coherency is maintained between the dedicated caches of a chip multiprocessor by writing back data from one dedicated cache to another without routing the data off-chip. Various specific embodiments are described, using write buffers, fill buffers, and multiplexers, respectively, to achieve the on-chip transfer of data between dedicated caches.

摘要： A method for detecting errors in a processing device is disclosed. A data source unit of a processing device transmits data and a qualifier synchronously with the data, the qualifier to indicate the data is uncorrectable. At least one intermediate functional unit in the processing device receives the data and the qualifier. The at least one intermediate functional unit detects the data is uncorrectable based on the qualifier. The at least one intermediate functional unit transmits, without using, the data and the qualifier synchronously with the data to a data consumer unit of the processing device. The data consumer unit receives the data and the qualifier. The data consumer unit detects the data is uncorrectable based on the qualifier. The data consumer unit maintains, without using the data and the qualifier.

摘要： Parity and mask bit(s) are stored in a random access memory (RAM) that is coupled to a CAM. This CAM may be part of a TLB. The parity and mask bits(s) are stored in conjunction with the CAM entry write. Upon a CAM query match, the reference parity bit(s) and mask bit(s) stored at the address output by the CAM are output from the RAM. These reference parity bit(s) are compared to parity bit(s) generated from a query data value that is masked by the retrieved mask bit(s). In the absence of a CAM or RAM bit error, the reference parity bit(s) from the RAM and the parity bit(s) generated from the masked query data will match. If a CAM or RAM bit error occurred, these two sets of parity bit(s) will not match and thus an error will be detected. This error may be used as an indication that a false CAM match has occurred.
