Abstract
One embodiment of the present invention provides a system that supports multiple delayed read transactions. The system includes a host bus and a peripheral bus. The system also includes a receiving mechanism that is configured to receive a first request and a pipelined request that originate from the host bus and are directed to the peripheral bus. The first request and the pipelined request are stored in a first buffer and a second buffer. The system additionally includes a sending mechanism that is configured to send the first request to the peripheral bus, so that the first request is processed when the peripheral bus becomes available. If the pipelined request is received and if the pipelined request is a read operation, the sending mechanism is configured to send the pipelined request to the peripheral bus, so that the pipelined request will be processed when the peripheral bus becomes available. The system also includes a retry mechanism that issues a retry request across the host bus that causes both the first request and the pipelined request to be retried at a later time on the host bus so that the host bus can be freed up for other transactions.
