Abstract

In accordance with the present invention, there is provided a register-modelled radio system comprising a plurality of register-modelled processors having addressable registers for modelling the virtual state of the processor; a serial bus, interconnecting the register-modelled processors for communicating between the addressable registers; and a communications protocol for passing information to or from the addressable registers, whereby the virtual state of a radio portion may be determined or altered by, respectively, communicating information from or to the addressable registers. The communications protocol further comprises an information packet having an address, an operation code, optional data, and an error detection device, such as a cyclical redundancy check packet. The operation code is chosed from the group of primitive operation codes reset, read, write, bit set, bit clear, acknowledge, and negative acknowledge.

Claims

1. A register-modelled radio system having a plurality of interdependent radio portions comprising:

register means for determining or altering the virtual state of a portion of a radio according to parametric data passed to it and

communication means, coupled to said register means, for communicating parametric data to or from said register means,

whereby the virtual state of said radio portion may be determined or altered by, respectively, communicating parametric data form or to said register means.

5. A register-modelled radio system as claimed in claim 1, 2 or 3 wherein said register means comprises a peripheral device for a mobile radio.

6. A register-modelled radio system as claimed in claim 1, 2 or 3 wherein said communication means further comprises a serial bus.

7. A register-modelled radio system as claimed in claim 1, 2 or 3 wherein said register means are addressable.

9. A register-modelled radio system as claimed in claim 1, 2, 3 or 8 wherein said parametric data comprises an operation code.

2. A register-modelled radio system having a plurality of interdependent radio processors comprising:

at least one register-modelled processor means for determining or altering the virtual state of said processor according to parametric data passed to it;

communication means, coupled to said register-modelled processor means, for communicating parametric data to or from said register-modelled processor means; and

other processor means, coupled to said communication means, for communicating with said register-modelled processor,

whereby the virtual state of said radio processor may be defined or altered by, respectively, communicating parametric data from or to said register-modelled processor means.

3. A register-modelled radio system having a plurality of interdependent radio processors comprising:

a plurality of register-modelled processor means for determining for altering the virtual state of said processor according to parametric data passed to it; and

communication means, interconnecting said register-modelled processor means, for communicating said register processor means,

whereby the virtual state of said radio processor may be determined or altered by, respectively, communicating parametric data from or to said register-modelled processor means.

4. A register-modelled radio system as claimed in claim 3 wherein said plurality of register-modelled processor means comprises multiple radio frequency modems.

8. A register-modelled radio system having a plurality of interdependent radio processors comprising:

a plurality of register-modelled addressable processor means for determining or altering the virtual state of said processor according to parametric data passed to it and

communication means, comprising a serial bus, interconnecting said register-modelled processor means, for communicating between said addressable register-modelled processor means,

a communications protocol for passing said parametric data to or from said addressable register-modelled processor means, comprising an information packet, further comprising;

an address

an operation code, further comprising;

a primitive operation code chosen from the group of primitive operation codes;

reset, read, write, bit set, bit clear, acknowledge, and negative acknowledge,

optional data, and

error detection data, further comprising;

a cyclical redundancy check packet,

whereby the virtual state of said processor may be determined or altered by, respectively, communicating parametric data from or to said addressable register-modelled processor means.
