Federico Faggin: The Real Silicon Man

While doing research for our articles about inventing the integrated circuit, the calculator, and the microprocessor, one name kept popping which was new to me, Federico Faggin. Yet this was a name I should have known just as well as his famous contemporaries Kilby, Noyce, and Moore.

Faggin seems to have been at the heart of many of the early advances in microprocessors. He played a big part in the development of MOS processors during the transition from TTL to CMOS. He was co-creator of the first commercially available processor, the 4004, as well as the 8080. And he was …read more

Bespoke Processors Might Soon Power Your Artisanal Devices

Modern microprocessors are a marvel of technological progress and engineering. At less than a dollar per unit, even the cheapest microprocessors on the market are orders of magnitude more powerful than their ancestors. The first commercially available single-chip processor, the Intel 4004, cost roughly $25 (in today’s dollars) when it was introduced in 1971.

The 4-bit 4004 clocked in at 740 kHz — paltry by today’s standards, but quite impressive at the time. However, what was remarkable about the 4004 was the way it shifted computer design architecture practically overnight. Previously, multiple chips were used for processing and were selected …read more
