Abstract:
A retry system for a PCI (peripheral component interconnect) agent in a PCI bus system, comprising:an initiator agent adapted to couple to a PCI bus, said initiator agent further adapted to communicate via said PCI bus with a target agent by initiating a data transaction;a retry identification register coupled to said initiator agent, said retry identification register adapted to store a target address and a transaction type corresponding to said target agent when said target agent issues a retry to said initiator agent; anda completion counter register coupled to said initiator agent, said completion counter register adapted to measure a latency period of said target agent, said latency period provided to said initiator agent such that said initiator agent efficiently completes a subsequent access corresponding to said target address and said transaction type by initiating said subsequent access at the expiration of said latency period.
