Asynchronous Interface For Communications Between Computing Resources That Are In Different Clock Domains

A method performed by a data transmitting computing resource operating in a first clock domain of a computing system, the method comprising:

• determining that a data receiving computing resource operating in a second clock domain of the computing system different from the first clock domain has granted a request to perform one or more data transfers to transmit a data packet to the data receiving computing resource;
• after determining that the data receiving computing resource has granted the request, placing data corresponding to a data transfer of the one or more data transfers on a parallel data channel comprising a plurality of data lines connecting the data transmitting computing resource and the data receiving computing resource;
• waiting a predetermined amount of time after the placing of the data corresponding to the data transfer on the parallel data channel, the predetermined amount of time based on different propagation times of the plurality of data lines;
• and
• after waiting the predetermined amount of time, notifying the data receiving computing resource that the data placed on the parallel data channel are valid.
