Abstract
Dataflow control for an application with timing parameters, including interfacing temporal and non-temporal domains, is described. The domains receive input data to a first dataflow network block, which is processed for untimed output of first tokens. The first tokens are obtained by a memory interface for timed writing of data portions of the first tokens to data storage and for timed reading of the data portions therefrom. Sending of the data portions read to a first queue of a first controller block is untimed, and the data portions are output by the first controller block with physical timing parameters. Second tokens are generated by the first controller block responsive to the physical timing parameters. The second tokens are fed back to a second queue of the first dataflow network block to control rate of generation of the first tokens by the first dataflow network block.
