Abstract:
A method for interfacing between a rate adaptation processing unit (RAPU) and a board messenger processing unit (BMPU) in a wireless data communication processing devices, said method comprising the steps of:in response to a group of protocol data (PD) transferred from one communication system to another communication system, forming a common header field having a rate adaptation (RA) header and a board message (BM) header and a data field in a predetermined area of a data buffer, wherein said common header field is commonly shared by a rate adaptation (RA) protocol and a board message (BM) protocol; setting a protocol offset for said RA header and said BM header in a predetermined area of said common header field to designate the start of said RA header and said BM header, and setting the first address of each said RA header and said BM header by a message pointer, respectively, to indicate the beginning point for receiving said group of said protocol data in said data buffer; processing said common header field by either said rate adaptation processing unit or said board message processing unit for transmission, depending on flow direction of said group of said protocol data between said one communication system and said another communication system; and, transmitting said processed common header field and said data field via a queue interface disposed between said rate adaptation processing (RAPU) and said board messenger processing unit (BMPU), and thereafter locating said message pointer at the first address of said common header for receiving next set of said protocol data in said data buffer.
