Techniques for On-Line Fault Monitoring in Modular Digital Systems.

As digital electronic systems have become more complex, the importance of techniques for detecting faults using internal system resources has increased. Viable alternatives to heretofore ad hoc built-in-test approaches are described in this report. The following fault detection techniques and assessment methods are discussed 1 Sample Fault Monitoring, 2 Programmable Cellular Arrays with Hardware Encoded Built-In-Test Facilties, 3 Mathematical Models for the Design and Analysis of On-Line Built-In-Testing, 4 A Flexible Fault-Tolerant Multiprocessor Architecture for Video Graphics.
