Automated Test for a Processor

The automated test equipment shown is comprised of a combination of interacting hardware and software packages. The equipment is capable of simulating a printer keyboard device insofar as the handling of control signals, data processing and responses is concerned.

The hardware package consists of an adapter unit 1 having an interface and cables 2 to a processor unit 3, which includes both a central processing unit (CPU) section 4 and a printer attachment 5. The adapter unit 1 includes an adapter unit 6 for the CPU 4 and another adapter 7 for the printer attachment 5 of processor 3, and has the necessary logic to monitor, activate, and control all of the lines originating from the CPU 4 and printer attachment 5.

A controller 10 which may be a part of a large data-processing system or a separate dedicated unit, is loaded with a group of test programs in a software package. This package operates the controller 10, to simulate both the printing and keyboard functions of the printer which will attach to the processor attachment 5 and tests for the proper processor responses. The controller 10 will also create simulated error conditions and malfunctions to enable a thorough check of the error-detecting circuitry of the attachment 5. The programs of controller 10 are also arranged to operate through the CPU adapter 6 to set the console switches of the processor 2 to enter instructions for programs, which will exercise control by the CPU 4...
