PATTERN DETECTOR FOR DETECTING HANGS |
| 摘要 |
A microprocessor comprises a cache including a tag array; a tag pipeline that arbitrates access to the tag array; and a pattern detector. The pattern detector comprises a register; a decoder that decodes transaction type identifiers of tagpipe arbs advancing through the tag pipeline; and an accumulator that accumulates into the register the transaction type identifiers of a plurality of tagpipe arbs that advance through the tag pipeline. |

1. A microprocessor comprising:
a cache including a tag array; a tag pipeline that arbitrates access to the tag array; and a pattern detector, the pattern detector comprising:
a register;a decoder that decodes transaction type identifiers of tagpipe arbs advancing through the tag pipeline, wherein tagpipe arbs are transactions to access the tag array; andan accumulator that accumulates into the register the transaction type identifiers of a plurality of tagpipe arbs advancing through the tag pipeline;wherein the pattern detector accumulates a history of the kinds of tagpipe arbs advancing through the tag pipeline. |
