Abstract:
A method and apparatus for handshaking using a 2-wire protocol is described. An electronic component may be divided into blocks, with the blocks performing one or more functions. The blocks may be in series with one another to form a pipeline. The blocks may use interface circuitry to transfer information upstream from or downstream to another block. The interface circuitry uses the 2-wire handshaking for the transfer including a transmit readiness wire configured to carry a signal indicative of readiness of the upstream circuit to output data and a receive readiness wire configured to carry a signal indicative of readiness of the downstream circuit to receive the data.
