the architecture and some basic applications of a single-chip software-programmable digital signal processor are presented. this NMOS 3.5 um silicon gate circuit is well-suited for adaptive algorithms and some input and output features allow easy implementation of multiprocessingarchitectures using several chips. these I/O ports are designed to transfer data serially or through an 8-bit bus. their main feature is control of an internal program or transfer of instructions from an external memory without any loss of speed. this circuit incorporates a 16×16 bit hardware multiplier, a powerful unit to compute the addresses of two 128×16 bit RAMs and a 32-bit arithmetic and logical unit with accumulator and stack, all of which are connected by two data buses (16 and 25b wide). Either 16- or 25- bit words can be processed using this circuit.

Approaching rapidly on the horizon is a change to parallel architecture in digital computers that has the potential for multiplying the speed of execution achieved in serial architectures. the departure from serial operations provides rather obvious improvements in execution times for operations that are repetitive and that can be performed independently of each other. Such operations arise frequently in signal processing programs and in mathematical programming algorithms. Of interest to this conference is the impact of the new architectures on the practice of simulation - particularly simulations of large physical systems. A large number of questions can be raised (but few answered) on the impact of the new machines on simulation model designs, languages, data base manipulation, and other questions on the general utility of such machines for simulation problem solving. Moreover, it is likely that the new machines will influence the design of simulation experiments, random number generation, strategies for statistical iterations, sensitivity analyses, and variance reduction methods. Because of the interdisciplinary nature of these topics a dialog between simulation practitioners and computer technology developers will grow in importance. Several panelists, consisting of a mixture of simulation practitioners and computer scientists will describe their recent experiences in simulating systems on parallel computer configurations, highlighting efficiency comparisons and speculating on the general utility of such machines for simulation enterprises.
the continuing evolution of microelectronics provides the tools for developing new methods of synthesizing digital images by utilizing parallelprocessingarchitectures which hold the promise of reliability, flexibili...

Hardwired resource allocators for TRAC-like reconfigurable architectures are described. these allocators facilitate searching for available resources in the system and allocation of a subset of these to a given request. Various algorithms can be implemented for the search and the allocation of the resources. Tree-structured allocators look particularly attractive withthe cost-delay product being of the order of M* (log M)**2 for a system with M resources of the same type. It is shown how this scheme can be extended to allocate multiple type of resources in the system.

In recent years ″software engineering″ has emerged as a discipline of programming. It includes the conceptualization, design, implementation, testing and modification of software systems. Related issues are languages, standards, distributed and parallelprocessing, and total programming environments. the fact that more than 80 percent of system development costs were in software rather than hardware helps one appreciate the importance of any effort to understand and enhance the software production process. Many pattern recognition projects involve fairly large software efforts. It makes sense not only for researchers to make use of the latest software tools and methodologies but also to anticipate future changes.
