Abstract
System and method transfer information from a primary processor to a co-processor. The primary processor includes an encoder, and the co-processor includes a decoder. To transfer information from the primary processor to the co-processor according to one embodiment of the present invention, the encoder in the primary processor creates an information word. An information word includes a plurality of bits, where each bit corresponds to a different type of information. The encoder sets the state of each bit to indicate whether information corresponding to that bit will be sent. The encoder then sends the information word, followed by the actual information. The decoder decodes the information word to determine what information will be arriving from the co-processor. The decoder identifies the information by the order in which it is received. Each different type of information is pre-assigned to a different register address in the co-processor. After the decoder identifies the information, it determines the address associated with that information.
