Can Market Dominance Trump Better Technology? A Case Study Arani Bhattacharya

Microprocessor Market in the 80s Electronic industry made rapid progress ▫Complex circuits in processors feasible Processor instructions (instruction set) became more and more complex Trend widely expected to continue ▫High Level Language Computer Architecture proposed

Expectations proved to be wrong More complex instructions naturally had to predict user programs behavior User programs behaved in unexpected ways Larger memory allowed large programs Architects proposed going back to simpler instructions

Overlapping of execution stages made possible

Caught up in this game was… Intel

The plight of Intel in the late 80s Other companies saw an opening ▫Apple ▫Motorola ▫IBM ▫Sun Microsystems ▫DEC

Intel Responds By doing nothing ▫High market share allowed Intel to carry on Waited for: ▫More improvements in electronics ▫Made it possible to simply instructions internally within the processor ▫Finally, implemented in 1989

Response Yes: Consensus among architects in academia and industry No: Intel

Conclusion Market does not always side with the best technology ▫Inertia can trump better technology Industry player with dominant market share can get away with inferior technology
