Abstract: Systems, methods, and computer-readable media are described for performing data compression in a manner that does not require software to make a call to hardware to close a compressed data block, thereby reducing computational overhead. In response to a request from software to data compression hardware for a data encoding, the hardware may return the data encoding as well as an end-of-block symbol encoding value and bit length. The hardware may load the end-of-block symbol encoding value and bit length into a different area in the returned structure such that the software has direct access to the value. When the software determines that a block should be closed, the software may retrieve the end-of-block symbol and insert it into the block without needing to make a call to hardware. The software may then make a call to the hardware to request a new data encoding for subsequent compressed data blocks.

Abstract: A computer-implemented method includes writing, by a producer, data to one or more buffers. The one or more buffers include a plurality of cells and together form a circular buffer, and an input cursor indicates which cell of the plurality of cells the producer writes to. The method further includes reading, by a consumer, data from the one or more buffers, where an output cursor indicates which cell of the plurality of cells the consumer reads from. It is detected that the consumer is overrun by the producer. A throughput of the consumer is compared to a throughput of the producer, responsive to detecting that the consumer is overrun by the producer. The output cursor is synchronized to a new position, by a computer processor, where the new position is selected based on comparing the throughput of the consumer to the throughput of the producer.
