The key benefit of the microprocessor results from integrating all of the components of a computer that are involved in executing instructions together on the same microchip. Instructions are fetched from external memory though often today this is cache memory on the same chip and data are loaded and stored from external memory again, often using on-chip caches , but the instruction decode and execute logic is all collocated, resulting in significant performance and energy benefits compared with splitting the processing functions across two or more chips, as was done prior to the arrival of the microprocessor.

These benefits accrue because on-chip connections incur much lower parasitic capacitance than do off-chip connections, and most of the delays and energy consumed by a processor result from driving capacitive loads up and down during execution. In this Perspectives paper, I will offer a personal view of the key developments in the history of the microprocessor, which can be divided quite cleanly into decade-by-decade progress.

This is not an exhaustive history, but an attempt to highlight the key issues as they emerged, and it starts in the s.

Intel came back with a counter-proposal to develop just four chips, one of which could be programmed to meet the needs of the range. That programmable chip was the Intel The microprocessor was born. It could be clocked at frequencies up to kHz and would execute up to 92 instructions per second.

It was a 4-bit device defined by the 4-bit width of the data bus , with 8-bit instructions and a bit address bus, all integrated into a pin dual-in-line package. From this modest start, a new era did, indeed emerge! Through the s, a diverse range of microprocessors were developed, the great majority of which were 8-bit devices with bit address buses packaged in pin dual-in-line packages. These included direct descendants of the such as the Intel and the , the Signetics my first microprocessor, now largely forgotten!

The drove down the price to new levels of affordability, and together with the Z80 was largely responsible for the emergence of the computer hobbyist movement which in turn led to the home computer revolution of the s.

Thanks to the 8-bit microprocessor, the computer was now out of the hands of the white-coated computer operator employed by the large corporation, and into the hands of the young enthusiast—students and entrepreneurs. When those young enthusiasts included the likes of Steve Jobs and Steve Wozniak creating the Apple 1, the seeds of change were well and truly sown.

The s: RISC versus complex instruction set By the beginning of the s, the PC market was established, and it was beginning to break out from its hobbyist origins into the wider home market, with basic computer familiarity and gaming being the primary uses in the home. These machines used 8-bit microprocessors, but there was a clear roadmap up to bit microprocessors.

Only Apple offered some credible degree of competition. Thus, the PC was established, and the scene was set for the microprocessor manufacturers to move their customers up to bit machines, as more performance would clearly sell more machines. But how should a bit machine be architected?

Computing without Clocks: Micropipelining the ARM Processor

The established microprocessor manufacturers were all large semiconductor companies who knew a lot about making chips but far less about computer architecture. There was a readily available source of architectural insight into how to configure a bit machine as the minicomputer business had been there before.

It did not use a microprocessor, but it showed how to architect such a machine using a multi-chip processor, and why should not a microprocessor do something similar? But some folk had other ideas! In , David A. Patterson and David R. Their arguments were strong, and were backed up by a real chip design—the Berkeley RISC I—that was being designed by a postgrad class in one session. The fundamental case was that an architecture based on a s minicomputer would have a very complex instruction set CISC!

With RISC that complexity was reversed; by keeping the instruction set as simple and regular as possible, no microcode ROM would be required, so there were more transistors available for architecture features that gave more benefit, such as a full bit instruction set and pipelined execution which was also facilitated by the regular instruction set.

The mainstream microprocessor manufacturers were unconvinced by all of this academic argument, and indeed spent most of the s expressing their firm opposition to the concept though by the end of the s most had succumbed and had some sort of in-house RISC project underway.

However, away from the mainstream, smaller companies considering designing their own processors lapped this all up. One such company was Acorn Computers in Cambridge, UK, who were responsible for the design of the very successful BBC Microcomputer, and were struggling to see how they should move up to bit processing.

At its peak, Acorn employed around staff and some in-house chip design expertise, and they had worked closely with VLSI Technology, Inc. The emerging bit microprocessors had significantly inferior real-time capabilities.

The most expensive component in a PC was the memory, but the bit processors of the day could not make full use of the bandwidth offered by those memories—surely a mistake?

So the Acorn team had started to think about designing their own microprocessor to overcome these perceived deficiencies. The ARM was designed from the outset as a bit machine, so Acorn largely skipped the bit generation.Steve Furber Publisher: Archived from the original PDF on 7 January In addition to the contributed papers, a number of mini-symposia were held, each focusing on one research theme.
