Internal Paper, MIT, Cambridge, Massachusetts. The introduction of SIMD instruction sets (Peleg et al.Įdinburgh Univ. This was appropriate when processors worked this way, but has become an impediment to programmers seeking to make use of the performance offered by multi-media instruction -sets. Whereas processor architectures are moving towards greater levels of parallelism, the most widely used programming languages such as C, Java and Delphi are structured around a model of computation in which operations takeplace on a single value at a time. The level or parallelism supported ranges from two floating point operations, at a time on the AMD K6 architecture to 16 byte operations at a time on the Intel P4 architecture. These instruction-set extensions are typically based on the Single Instruc tion-stream Multiple Data-stream (SIMD) model in which a single instruction causes the same mathematical operation to be carried out on several operands, or pairs of operands, at the same time. Such instruction-sets have been incorporated both in specialist DSPchips such as the Texas C62xx (Texas Instruments, 1998) and in general purpose CPU chips like the Intel IA32 (Intel, 2000) or the AMD K6 (Advanced Micro Devices, 1999). The aim is to allow operations to proceed on multiple pixels each clock cycle.

This conference discussed computer software systems in banking, commercial, technical, industrial, and university environments which resulted in particularly stimulating discussions, which are included with these proceedings. There will be a need for software for a variety of purposes, and will no doubt become even more specialized over time. Now it can be clearly seen that computer systems are going to become more complex, both front and rear end processors are going to be attached on the main frame computer to provide communication networks, interactive graphics, etc.
The aim of these conferences is to present practical exposition on computers, computing, and software to foster user acceptance.
