Detection of Unidirectional Multiple Errors Using Low-Cost Arithmetic Codes

We show that a low-cost arithmtetic code with group length n detects all unidirectional multiple errors that affect fewer than n bits, as well as a larger class of such errors confined to a restricted set of bit positions.

Transient Failures in Triple Modular Redundancy Systems with Sequential Modules

The effects of transient failures in sequential modules in systems using triple modular redundancy (TMR) cannot be neglected. A transient may place a sequential machine in an erroneous state, and the state may remain erroneous long after the transient has disappeared. We show that the state of a sequential machine can be restored after a transient if and only if the machine has a synchronizing sequence. If synchronizing sequences occur periodically during normal operation of the system, then multiple transients spaced out in time can be tolerated. System structures that have synchronizing sequences are discussed.

Microcomputers in the Computer Engineering Curriculum

Microcomputers are the most important new building block for electronic systems to emerge since the integrated circuit operational amplifier. It is obvious that colleges and universities should incorporate microcomputers into existing electrical and computer engineering curricula; but not surprisingly, there exists some dispute about the best way to do this. Before describing the approach at Stanford, we will discuss the philosophy upon which our curriculum is based.

Microprocessor Input/Output Architecture

There are at least as many different microprocessor input/output organizations, circuit configurations, and device types as there are microprocessor families and manufacturers. Due to the diversity of competing approaches and devices, their similarities and differences are not always evident. The fact that each manufacturer describes his approaches and devices differently, and the relative scarcity of formal text material on microprocessors, do not make the situation any better. In this short space there is no hope of comprehensively surveying all available approaches and devices (nor would I want to, even if space were available!). On the other hand, I can present an overview of basic microprocessor I/O organization and typical circuit configurations and devices. Using these concepts as a basis, one may be able to make comparisons between current and future approaches available commercially.

Logic design education at Stanford University

Recent developments in the logic design courses in the Computer Systems Laboratory at Stanford University are described. The courses include an introductory undergraduate lecture and laboratory course, an advanced undergraduate laboratory, and a graduate lecture and CAE (computer-aided engineering) laboratory course.<<ETX>>
