to provide a communications bus or a central core which
contains an interface with the communications bus, an encoder
and switching matrix.
We next consider the 35 U.S.C. § 103 rejection of claims
18 and 19. We find that the Examiner has failed to present a
prima facie case of obviousness. As identified above we find

bus and core containing an interface with the communication
bus, a decoder and two additional buses to transmit the
decoded data from the core to the signal processor. We find
that the Examiner has failed to show that each limitation of
the claims is taught in the prior art. We find that Engels
fails to disclose a core which interfaces with a
communications bus, decodes data received from the
communications bus and transmits the data to the signal
processor. Further, we find that Examiner has not shown that
