Abstract
Abstract 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 chosen from the group of primitive operation codes reset, read, write, bit set, bit clear, acknowledge, and negative acknowledge.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
A method of communicating information between a plurality of register-modelled processor means cooperatively operating within a radio device, comprising the steps of: (a) generating, in any of the plurality of register-modelled processor means, an information packet having at least an operation code and an argument, (b) transmitting, serially, said information packet to at least one of the plurality of register-modelled processor means over a serial communication link, (c) receiving, serially, said information packet from said serial communications link, (d) performing the operation designated by said operation code in cooperation with said argument.
Claim 2
Independent Claim
92 words
A method of communicating information between a plurality of register-modelled processor means cooperatively operating within a radio device, comprising the steps of: (a) generating, in any of the plurality of register-modelled processor means, an information packet having at least an operation code and an argument, (b) transmitting, serially, said information packet to at least one of the plurality of register-modelled processor means over a serial communication link, (c) receiving, serially, said information packet from said serial communications link, (d) performing the operation designated by said operation code in cooperation with said argument.
Claim 3
Dependent Claim
59 words
A method as claimed in claim 1 wherein said register-modelled processor means have predetermined addresses and wherein said generating and said preforming steps further comprise, respectively, the steps of: generating an information packet further having an address corresponding to another register-modelled processor means, and performing said operation when said address corresponds to said receiving register-modelled processor mean's predetermined address.
Claim 4
Dependent Claim
55 words
A method as claimed in claim 1 wherein said generating and said performing steps further comprise, respectively, the steps of: generating an information packet further having a register address, and performing said operation in cooperation with said addressed register when said address corresponds to a register defined within said receiving register-modelled processor's mean's register set.
Claim 5
Dependent Claim
68 words
A method as claimed in claim 1 wherein said generating and said performing steps further comprise, respectively, the steps of: generating an information packet further having a register address and having data as an argument to said operation code, and performing said operation upon said data in cooperation with said addressed register when said address corresponds to a register defined within said receiving register-modelled processor mean's register set.
Claim 6
Dependent Claim
35 words
A method as claimed in claim 1 wherein said operation code is a primitive operation code chosen from the group of primitive operation codes: reset, read, write, bit set, bit clear, acknowledge, and negative acknowledge.
Claim 7
Dependent Claim
17 words
A method as claimed in claim 1 wherein said information packet further comprises: an error detection device.
Claim 8
Dependent Claim
20 words
A protocol as claimed in claim 6 wherein said error detection device further comprises: a cyclical redundancy check (CRC) packet.
Claim 9
Dependent Claim
132 words
A register-modelled radio device, having addressable register means, comprising: a plurality of register-modelled processor means having addressable register means for modelling the virtual state of said processor and communication means, comprising a serial bus, interconnecting said register-modelled processor means, for communicating between said addressable register means, a communications protocol for passing information to or from said addressable register means, comprising an information packet, further comprising: an address, an operation code, further comprising: a primative operation code chosen from the group of primatives: reset, read, write, bit set, bit clear, acknowledge, and negative acknowledge, optional data, and an error detection device, further comprising: a cyclical redundancy check packet, whereby the virtual state of said register-modelled processor means may be determined or altered by, respectively, communicating information from or to said addressable register means.
Claim 10
Dependent Claim
132 words
A register-modelled radio device, having addressable register means, comprising: a plurality of register-modelled processor means having addressable register means for modelling the virtual state of said processor and communication means, comprising a serial bus, interconnecting said register-modelled processor means, for communicating between said addressable register means, a communications protocol for passing information to or from said addressable register means, comprising an information packet, further comprising: an address, an operation code, further comprising: a primative operation code chosen from the group of primatives: reset, read, write, bit set, bit clear, acknowledge, and negative acknowledge, optional data, and an error detection device, further comprising: a cyclical redundancy check packet, whereby the virtual state of said register-modelled processor means may be determined or altered by, respectively, communicating information from or to said addressable register means.
