  • Circular buffer architecture using local memories with limited resources
    Patent number: 11954359
    Abstract: A circular buffer architecture includes a memory coupled to a producer circuit and a consumer circuit. The memory is configured to store objects. The memory can include memory banks. The number of the memory banks is less than a number of the objects. The circular buffer can include hardware locks configured to reserve selected ones of the memory banks for use by the producer circuit or the consumer circuit. The circular buffer can include a buffer controller coupled to the memory and configured to track a plurality of positions. The positions can include a consumer bank position, a consumer object position, a producer bank position, and a producer object position. The buffer controller is configured to allocate selected ones of the objects from the memory banks to the producer circuit and to the consumer circuit according to the tracked positions and using the hardware locks.
