Patent ID: 7426650

Claim:
An asynchronous wrapper wherein the asynchronous wrapper is responsible for a conversion of an asynchronous communication of an associated locally synchronous circuit block with an external other locally synchronous circuit block having its own asynchronous wrapper, the asynchronous wrapper comprising at least one input unit which is adapted to receive a request signal from outside the asynchronous wrapper and to indicate to the outside the reception of the request signal by the delivery of an associated acknowledgement signal, and a pausable clock unit which is adapted to repeatedly produce a first clock signal and deliver it to an internally synchronous circuit block associated with the asynchronous wrapper, characterised in that the input unit is adapted to produce, if a request signal is applied, a second clock signal which is in a defined time relationship with the request signal and to deliver it to the internally synchronous circuit block, and there is provided a time-out unit which is connected to the input unit and which is adapted to suppress delivery of the first clock signal to the favor of the delivery of the second clock signal.
