Title: Multilevel cache structure and method using multiple issue algorithm with over subscription avoidance for high bandwidth cache pipeline
Inventor: MULIA DEAN A
IPC: G06F12/08
Filed: 2000-09-27
Granted: 2005-07-11
Abstract: A multi-level cache structure and associated method of operating the cache structure are disclosed. The cache structure uses a queue for holding address information for a plurality of memory access request as a plurality of entries. The queue includes issuing logic for determining which entries should be issued. The issuing logic further comprises find first logic for determining which entries meet a predetermined criteria and selecting a plurality of those entries as issuing entries. The issuing logic also comprises lost logic that delays the issuing of selected entry for a predetermined time period based upon a delay criteria. The delay criteria may, for example, comprise a conflict between issuing resources, such as ports. Thus, in response to an issuing entry being over subscribed, the issuing of such entry may be delayed for a predetermined time period (e.g., one clock cycle) to allow the resource conflict to clear.
