Hand Held Calculator Technology Applied to an Advanced Omega Receiver

A general description of the Autonetics two-frequency Omega receiver processor will be presented with emphasis on how calculator MOS/LSI circuitry has been applied to the automatic processing of Omega signals. The system functions and features will be outlined along with the method of operation.

The Structure of Management Decision Systems

The informatic approach looks at human thinking, organized activity, electronic data processing and management as symbolic phenomena, whose behavior is regulated by a multiplicity of models and programs, all of them instances of information systems; of course they differ because of the diversity of the hardware employed, and even more because of the enormous variety of problems encountered [Newell, Allen, Herbert A. Simon. 1972. Human Problem solving. Prentice-Hall, Englewood Cliffs, p. 870]. The symbolic solution to problems must be therefore understood along three lines [Newell, Allen, Herbert A. Simon. 1972. Human Problem solving. Prentice-Hall, Englewood Cliffs, p. 789]: (1) Description of problems presented by the task environment; this is the typical area of Operations Research, (2) Description of the man-machine processor, be it a group or an institution; Behavioral Sciences study the human processors, which may be significantly influenced by computer technology, and (3) Description of the program which is gradually compiled by the social processor to adapt itself to a task required by the environment. This is the enormous endevour to be undertaken by Management Science.

VDL—a Definition system for all levels

The VDL system for the description of programming languages which was originally used for the definition of PL/I is extended to the description of processors. This paper shows the relationship between the language of definition and the abstract machine over which the semantics of the language are specified. It is demonstrated that the level of description can be chosen to suit the various needs of the computing community, each level being well nested within its outer level, whilst using only one language of definition. From the point of view of processor design, indications are given of the means by which a description can be transformed into an implementable system of data paths, registers and drivers.

An equipment manufacturer's problems in the application of microelectronics

Modern radar equipment relies increasingly on data processing and statistical probability when presenting target information. This equipment must be reliable, with rapid check out and servicing capability. Microelectronics can be exploited to give this capability, especially when small size and low weight are also prime requirements. The paper compares the cost and estimated M.T.B.F. of an equipment using: 1. (a) Conventional components with soldered connexions, plugs and sockets. 2. (b) Conventional components, welded joints, no plugs or sockets. 3. (c) Microelectronic circuits, welded joints, plugs and sockets. The expected trends of cost and reliability are discussed. For a complete military equipment, microelectronics offers comparable reliability at lower cost after mid-1964. The unsatisfactory although rapidly improving situation of procurement of suitable United Kingdom microelectronic devices is discussed. Finally, the paper gives a brief description of a small data processor and compares cost, power consumption and reliability of a conventional production model with an integrated network prototype.
