Abstract: The recent advances in the integrated circuits technology have boosted the interest in task-oriented computer architechtures. The abailability of suitable microprocessors makes it affordable to combine many of them into powerful multiprocessor configurations. The high cost effectiveness of this kind of hardware, however is contradicted by disproportionale costs for the development of software. In this paper, the problems of software development are investigated for the context of small, low cost multiprocessor projects. The construction of a software support system, that is tailored to the particular architecture, is described. The development of a multiprocessor system for speech recognition (the Harpy Machine) is used as an example for demonstrating how such a software support system can be based on a general purpose time sharing system (UNIX) and its facilities.

The role of simulation in the development of task-oriented computer architectures
R. Bisiani
- 01 Apr 1979
TL;DR: This paper is concerned with one approach to the problem of software development: the use of an ad-hoc simulator as a cheap software development tool (as opposed to the typical use of a simulator as an design evaluation tool).

Microprocessor realization of a linear predictive vocoder
TL;DR: The goal was a low-power, low-cost, compact special-purpose realization of a narrow-band speech terminal, and the resultant design is a general-purpose two-bus structure running at a 150 ns cycle time.

The switching structure and addressing architecture of an extensible multiprocessor: cm*.
Richard James Swan
- 01 Jan 1978
TL;DR: The hierarchical switching structure of Cm* offers, in principle, indefinite extensibility of processing power, memory capacity and communication bandwidth and the cost of the interconnection structure grows approximately linearly with system size.
