Research in the Digital Systems Laboratory: August 1976 - July 1977
註釋Research investigations were concentrated in the following areas: Computer Reliability and Testing, including detection of intermittent failures, testing for sequential circuits, self-checking linear feedback shift registers, simulation analysis of high-reliability systems, effects of failures on gracefully degradable systems, fault diagnosis in digital systems, and software reliability; Critical Fault-Pattern Determination; Computer Architecture, including trace facility, memory interleaving, and monitors for signal activity; Organization of Computer Systems, including an emulation research laboratory, emulators, and memory performance; Feasibility of Real-Time Emulation, including directly executable languages; Distributed Date Processing for Ballistic Missile Defense; Description Languages and Design for General-Purpose Computer Architectures, including evaluation of existing hardware description languages, development of a structural description language, applications of the structural design language, bounds for maximal parallelism, and parallel information processing in bilogical systems; Computer Networks, including broadcast protocols in packet-switched computer networks and the optimal placement of dynamic-recovery checkpoints in recoverable computer systems; Design and Verification of Reliable Software including specifications and proofs for abstract data types in concurrent programs, specification and verification of monitors, and operating system design; Design Automation, including a language for describing the structure of digital systems, the SPRINT printed-circuit design system, computer-aided layout of large-scale integrated circuits, and an interactive system for design capture; Database, including studies in distributed processing and problem solving, a database maintenance system, and the implementation of database in medicine; and Digital Incremental Computers.
