Abstract
Abstract A data processing unit diagnosis control apparatus comprises a microprocessor, a memory device, a data transfer circuit and a diagnostic processor. The diagnostic processor performs a diagnostic program of a data processing apparatus to be diagnosed. The diagnosis program is supplied from the memory device via the data transfer circuit under control of the microprocessor which issues an appropriate instruction to the data transfer circuit. The microprocessor is subsequently able to operate on other programs while the diagnostic processor executes the diagnostic program.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
A data processing unit diagnosis control apparatus comprising: a microprocessor for controlling processing of a service request, a transfer of data to and from a data processing apparatus to be diagnosed, and selection of a diagnostic program for a diagnostic maintenance operation; memory means for storing said diagnostic program and said data, said memory means accessible by said microprocessor; data transfer means for reading out said diagnostic program selected by said microprocessor and said data stored in said memory means and sending out the same in accordance with an instruction from said microprocessor, and for receiving the data from said data processing apparatus to be diagnosed and transferring the same to said memory means in accordance with said instruction from said microprocessor; and diagnostic processor means for performing diagnosis of said data processing apparatus to be diagnosed according to said selected diagnostic program and data sent from said data transfer means and communicating a status of the diagnosis to said microprocessor through said data transfer means, thereby performing said diagnostic maintenance operation.
Claim 2
Dependent Claim
172 words
A data processing unit diagnosis control apparatus comprising: a microprocessor for controlling processing of a service request, a transfer of data to and from a data processing apparatus to be diagnosed, and selection of a diagnostic program for a diagnostic maintenance operation; memory means for storing said diagnostic program and said data, said memory means accessible by said microprocessor; data transfer means for reading out said diagnostic program selected by said microprocessor and said data stored in said memory means and sending out the same in accordance with an instruction from said microprocessor, and for receiving the data from said data processing apparatus to be diagnosed and transferring the same to said memory means in accordance with said instruction from said microprocessor; and diagnostic processor means for performing diagnosis of said data processing apparatus to be diagnosed according to said selected diagnostic program and data sent from said data transfer means and communicating a status of the diagnosis to said microprocessor through said data transfer means, thereby performing said diagnostic maintenance operation.
Claim 3
Dependent Claim
