Abstract
Systems, methods, and computer program products for controlling a plurality of pipelined stages are described. In some implementations, an apparatus is described that includes a pipelined data path including a plurality of adjacent stages, where a stage includes a data store, a valid indicator, and a transfer controller including a state machine having a plurality of states. In some implementations, the stage is configured to send a status indicator different from the valid indicator to the state machine to indicate whether new data is available for processing by the stage in a next cycle, and whether a new data transfer is desired in the next cycle between the stage and the adjacent stage.
