ABSTRACT:
A split-architecture modem splits the physical layer protocol into a logical operations portion and a signal processing portion. A first processor (e.g., a general purpose processor (GPP)) of the modem performs the logical operations of the physical layer protocol along with the data link layer protocol. A second processor (e.g., a digital signal processor (DSP)) of the modem performs the signal processing portion of the physical layer protocol.
