Abstract
A write-only data transfer protocol for peripheral component interface busses and a method for transferring data between source and destination communication units is provided. The method includes the source communication unit writing a buffer allocation request to the destination unit and, in response to the buffer allocation request, the destination communication unit allocating space within an associated buffer to receive the data to be sent. The method also includes the destination communication unit writing at least the location of the allocated buffer to the source communication unit and the source communication unit writing the data to be sent to the allocated buffer location.
