Abstract
A load-store unit having one or more banked queues is disclosed. In one embodiment, a load-store unit includes at least one queue that is subdivided into multiple banks. Although divided into multiple banks, the queue logically appears to software as a single queue. A first bank of the queue includes a first plurality of entries, with the second bank of the queue having a second plurality of entries, wherein each of the entries is arranged to store memory instructions. Each of the banks is associated with corresponding logic circuitry that controls one or more pointers for that bank. The pointer information may be exchanged between the logic circuits associated with the banks. Based on the pointer information that is exchanged, each bank may output (e.g., for retirement) one entry per cycle.
