Multi-cycle resource sharing

摘要

Systems and methods for resource sharing of pipelined circuitry of an integrated circuit (IC) are provided. For example, in one embodiment, a method for sharing a functional unit of an integrated circuit (IC) includes receiving two or more threads configured to access the functional unit through two or more data entry points associated with corresponding data exit points configured to receive processed thread data. The method further includes arbitrating the processing of the two or more threads by the functional unit to obtain the processed thread data. To arbitrate, the exit points that cannot receive additional data are determined. Threads are only received from data entry points with corresponding data exit points that can receive additional data. The processed output data is provided to a corresponding exit point.

1. A method for sharing a functional unit of an integrated circuit (IC), the method comprising:
receiving two or more threads configured to access the functional unit through two or more data entry points associated with corresponding data exit points configured to receive processed thread data; arbitrating the processing of the two or more threads by the functional unit to obtain the processed thread data; and providing the processed output data to a corresponding exit point; wherein arbitrating the processing comprises:
determining data exit points that cannot receive additional data, andreceiving threads only from data entry points with corresponding data exit points that can receive additional data.
