Embodiments relate to providing a data stream interface for offloading the inflation/deflation processing of data to a stateless compression accelerator. An aspect includes transmitting a request to inflate or deflate a data stream to a compression accelerator. The request may include references to an input buffer for storing input data from the data stream, an output buffer for storing processed input data, and a state data control block for storing a stream state. The stream state is provided to the compression accelerator to continue processing the data stream responsive to the request being a subsequent request. The compression accelerator is instructed to store a current stream state in the state data control block responsive to the request being a non-final request. Accordingly, the current stream state is received from the compression accelerator responsive to the request being a non-final request. The processed input data is received from the compression accelerator.
