Asynchronous cladding circuit for a globally asynchronous, locally synchronous (gals) circuit

摘要

The present invention relates to an asynchronous cladding circuit for a global synachrone, locally synchronous circuit. The asynchronous cladding circuit operates with a driven by request signals clocking, supplemented in the absence of request signals by means of a local clock period. It has at least one input unit which is constructed to receive a request signal from the outside and the reception of the request signal by the release of an associated acknowledgement signal to indicate to, and a can clock period, which is formed a first clock signal to generate and repeated to one of the asynchronous cladding circuit associated, to deliver internally synchronous circuit block. The input unit is designed, in the case of a request signal a with the request signal in a defined time relationship with stationary second clock signal to produce and to deliver the internally synchronous circuit block. Furthermore, a connected with the input unit (timeout - unit is provided, which is formed, the release of the first clock signal in favor of the delivery of the second clock signal to suppress.
