Abstract
An apparatus for processing cache requests in a computing system is disclosed. The apparatus may include a pending request buffer and a control circuit. The pending request buffer may include a plurality of buffer entries. The control circuit may be coupled to the pending request buffer and may be configured to receive a request for a first cache line from a pre-fetch engine, and store the received request in an entry of the pending request buffer. The control circuit may be further configured to receive a request for a second cache line from a processor, and store the request received from the processor in the entry of the pending request buffer in response to a determination that the second cache line is the same as the first cache line.
