This paper investigates issues which impinge on the design of static instruction schedulers for micronet-based asynchronous processor (MAP) architectures. The micronet model exposes both temporal and spatial concurrency within a processor. A list scheduling algorithm is described which has been optimised with MAP-speciic heuristics. Their performance on some program graphs are presented and con...

This paper describes a NL data base interface which consists oF two parts: a Natural Language Processor (NLP) and a data base application program (DBAP). The NLP is a general pur!~se language processor which builds a formal representation of the meaning of the English utterances it is given. The DBAP is an algorithm with builds a query in a augmented relational algebra from the output of the NL...

The requirements on and the performance of holographic Fourier transform lenses for a matched-filter optical processor are discussed. The holographic aberrations were analyzed using a ray-tracing computer program, and holographic lenses were fabricated and assembled into an optical processor. Analysis and experimental results show that holographic optics are capable of processing images of larg...

This paper presents the New Systolic Language as a general solution to the problem systolic programming. The language provides a simple programming interface for systolic algorithms suitable for diierent hardware platforms and software simulators. The New Systolic Language hides the details and potential hazards of inter-processor communication, allowing data ow only via abstract systolic data ...

The design, implementation, and performance of two chess programs running on a multi-processor system are presented. Methods for distributing and enhancing the alpha-beta algorithm in a parallel environment are discussed. With the Principal Variation Splitting method, a four processor chess program yields a 3.35 fold speed-up over the sequential version. [Recreated from files dated 4 May 1984 i...

We present a program to simulate the dynamics of a wave packet interacting with a time-dependent potential. The time-dependent Schrödinger equation is solved on a one-, two-, or three-dimensional spatial grid using the split operator method. The program can be compiled for execution either on a single processor or on a distributed-memory parallel computer.

A simple method of measuring performance is by means of a benchmark program. Unless such a program is carefully constructed it is unlikely to be typical of the many thousands of programs run at an installation. An example benchmark for measuring the processor power of scientific computers is presented: this is compared with other methods of assessing computer power. (Received December

This paper covers the design technique of an enhanced Reduce Instruction Set Computer (RISC)-based processor core using application-specific instruction-set processor (ASIP) methodology. The processor core, called UTeMRISC03, is essentially a synthesizable processor written in Verilog HDL with a 16-bit data path and a 22-bit wide instruction. Using ASIP methodology, the processor architecture i...
