Systems and methods for efficient dynamic utilization of shared resources in a processor. A processor comprises a front end pipeline, an execution pipeline, and a commit pipeline, wherein each pipeline comprises a shared resource with entries configured to be allocated for use in each clock cycle by each of a plurality of threads supported by the processor. To avoid starvation of any active thread, the processor further comprises circuitry configured to ensure each active thread is able to allocate at least a predetermined quota of entries of each shared resource. Each pipe stage of a total pipeline for the processor may include at least one dynamically allocated shared resource configured not to starve any active thread. Dynamic allocation of shared resources between a plurality of threads may yield higher performance over static allocation. In addition, dynamic allocation may require relatively little overhead for activation/deactivation of threads. |
