Abstract
Abstract A system for transferring solicited message packets between data processors coupled on a serial communications path. A solicitor processor allocates a portion of its memory for storage of solicited message packets which might be solicited and received from at least one other data processor. The solicitor data processor defines a sequence of operations to be performed on any such received solicited message packets at that processor. The solicitor processor also transfers a solicited message parameter signal to the solicitee data processor where that signal is representative of a predetermined header portion for solicited data packets which might be generated by the solicitee data processor and transferred to the solicitor data processor. The header portion of a solicited message packet relates one or more of the sequences of operations which are to be associated with that packet. At least one of the other data processors receives any solicited message parameter signal addressed to that solicitee data processor. The solicitee processor is responsive to a received message parameter signal to generate a solicited message packet (with a header portion, as defined by the solicited message parameter signal) for transfer to the solicitor processor. The solicitor processor receives any such transmitted solicited message packet and stores that packet in the allocated portion of memory.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
291 words
A system for transferring solicited message packets from at least one solicitee data processor to at least one solicitor data processor, comprising: A. a plurality of data processors coupled on a serial communications path, each data processor including a central processing unit and an associated means for storing data, B. allocation means associated with at least one solicitor data processor for allocating a portion of its associated storage means for storage of solicited message packets to be received from at least one of said solicitee data processors, and means for defining a sequence of operations to be performed on said received solicited message packets at said solicitor data processor, at least one of said operations being the storage operation of storing a received solicited message packet in said allocated portion, each of said solicited message packets including a predetermined header portion relating said solicited message packet to one or more associated ones of said sequences of operations, C. solicitation means associated with said solicitor data processor for generating and transferring a solicited message parameter signal to at least one solicitee data processor, said solicited message parameter signal being representative of said predetermined header portion for said solicited message packet, D. solicited message packet transfer means associated with said solicitee data processor, including means for receiving said solicited message parameter signal, and means responsive thereto for generating said solicited message packet, said solicited message packet including at least a predetermined header portion, and including means for transferring said solicited message packet over said communications path to said solicitor data processor, and E. receiving means at said solicitor data processor for receiving said transferred solicited message packets from said communications path and for storing said received solicited message packets in said allocated portion.
Claim 2
Independent Claim
291 words
A system for transferring solicited message packets from at least one solicitee data processor to at least one solicitor data processor, comprising: A. a plurality of data processors coupled on a serial communications path, each data processor including a central processing unit and an associated means for storing data, B. allocation means associated with at least one solicitor data processor for allocating a portion of its associated storage means for storage of solicited message packets to be received from at least one of said solicitee data processors, and means for defining a sequence of operations to be performed on said received solicited message packets at said solicitor data processor, at least one of said operations being the storage operation of storing a received solicited message packet in said allocated portion, each of said solicited message packets including a predetermined header portion relating said solicited message packet to one or more associated ones of said sequences of operations, C. solicitation means associated with said solicitor data processor for generating and transferring a solicited message parameter signal to at least one solicitee data processor, said solicited message parameter signal being representative of said predetermined header portion for said solicited message packet, D. solicited message packet transfer means associated with said solicitee data processor, including means for receiving said solicited message parameter signal, and means responsive thereto for generating said solicited message packet, said solicited message packet including at least a predetermined header portion, and including means for transferring said solicited message packet over said communications path to said solicitor data processor, and E. receiving means at said solicitor data processor for receiving said transferred solicited message packets from said communications path and for storing said received solicited message packets in said allocated portion.
Claim 3
Dependent Claim
44 words
A system according to claim 1 wherein at least one of said solicitor data processors includes means for generating a packet received signal, said packet received signal being indicative of the receipt of a solicited message packet from one of said solicitee data processors.
Claim 4
Dependent Claim
43 words
A system according to claim 2 wherein said packet received signal generating means further includes means for generating said packet received signal whereby said packet received signal is indicative of the storage location of said received solicited message packet in said allocated portion.
Claim 5
Dependent Claim
44 words
A system according to claim 2 wherein said packet received signal generating means further includes means for generating said packet received signal whereby said packet received signal is indicative of the identity of the solicitee data processor which transmitted said received solicited message packet.
Claim 6
Independent Claim
36 words
A system according to claims 1 or 2 or 3 or 4 wherein at least one of said solicitor data processors includes means for performing said associated sequences of operations on said received solicited message packets.
