Implementation Resources

The computer configuration for the Defect Inspection System has a minicomputer to manage the interactions between the supervisor and the inspection surfaces and two microcomputers each managing two surfaces each. The supervisor will be provided with a single graphics terminal which is driven from the Product Management Minicomputer. This terminal will be used to change sheet sizes, the configuration, and the product standards for each surface. The computer is equipped with a hard disk and has two links to the microcomputers. A microcomputer controls the inspection surfaces monitored by a single operator. The start and stop buttons for each surface are a part of the control panel for each micro, but the signals are wired directly into the Product Management Computer. A link to the Product Management minicomputer is also provided. Figure D-BKG shows the overall configuration.

Figure D.BKG. Overall hardware configuration.

The software environment for the micro allows up to four tasks, none of which may be bigger than 32 Kb. A shared global memory area is available to all tasks. Tasks may wait on interrupts after activation, and may use an operating system service “Activate Task” to initiate other tasks in the system. The total memory for the micro is 128 Kb including the operating system, shared global memory area, and all tasks.

The minicomputer is capable of running any number of tasks, though only four may be resident in memory at any one time. Tasks may be swapped out of memory when not in use.
