In a streaming cache, multiple, dynamically sized tracking queues are employed. Request tracking information is distributed among the plural tracking queues to selectively enable out-of-order memory request returns. A dynamically controlled policy assigns pending requests to tracking queues, providing for example in-order memory returns in some contexts and/or for some traffic and out of order memory returns in other contexts and/or for other traffic.

Out of order memory request tracking structure and technique

In certain aspects of the disclosure, an apparatus comprises a first scheduling pool associated with a first minimum scheduling latency and a second scheduling pool associated with a second minimum scheduling latency, the second minimum scheduling latency greater than the first minimum scheduling latency. A common instruction picker is coupled to both the first scheduling pool and the second scheduling pool. The common instruction picker may be configured to select a first instruction from the first scheduling pool and a second instruction from the second scheduling pool, and then choose either the first instruction or second instruction for dispatch according to a picking policy.
