Multiprocessor system for preventing starvation in case of occurring address competition and method thereof |
摘要 |
A case occurs in which a preceding transaction to be retried cannot be retried as a result of snooping. If the snoop result is waited for so that a retry decision may be made after the result of snoop has been obtained, latency is prolonged to urge the pipeline to have a variable length, thus complicating the logic. A transaction determined to be retried in the phase of issue of a request is discriminated from a transaction in course of issue and when a transaction representing a starvation protection object sequentially competes twice with the transaction in course of retry decision, the transaction of starvation protection object is issued to thereby eliminate starvation.
