The need for parallel processing is felt in many disciplines. In this paper we discuss the essential issues involved in these systems. Various architectural proposals reported in the literature are classified based on the execution order and parallelism exploited. Design and salient features of some architectures which have gained importance are highlighted. Architectural features of non-von Neumann systems such as data-driven, demand-driven, and neural computers, which open the horizon for research in the new models of computations, are presented in this paper. Principles and requirements of programming languages and operating systems for parallel architectures are also reviewed.
