I ran across the IEEE Spectrum article “25 Microchips that Shook the World” this morning. I love history and especially tech history so I enjoyed the article very much. However, as is often the case in microelectronics, the article is written from a compute centric viewpoint and misses the mark widely on communications.
Let’s put out my bias. The most earthshaking invention of the last 25 years is the internet. The internet and it’s ‘world-wide’ reach has done more to re-shape our lives; the way we use time, the way we perceive other cultures and the ability to acquire new knowledge; than any other modern invention previous or since. After the internet, I put the cell phone in second. For 100 years the basic measure for economic development has been telecommunication infrastructure; bringing the ability to communicate to the population. Cellular has brought the ability to make a simple phone call to more people in the last 10 years then the entire history of telephony. I’m a communication zealot, these technologies have had huge and unquestionably positive impact on the human condition.
The internet was enabled in 1994 by a standard and the resulting chip development, the V.34 modem. The V.34 ITU standard was ratified in July of 1994. The V.34 standard introduced the breakthrough of Trellis coding and broke the 10Kbps bandwidth barrier over the phone line. In fact, with all features implemented, V.34 neared the Shannon theoretical limit for digital bandwidth over the phone line (~35Kbps). This was enough to make more than e-mail viable through the internet and, not coincidentally, the 1st version of the Netscape browser was announced in October of that same year, 1994. These events were followed by quick and significant commercial success. Rockwell, then one of the leaders in modem chip technology, generated about $3B in revenue in V.34 sales between 1995 and 1996 alone and Netscape completed one of the most sought after IPO’s in history on August 9, 1995. The next four years, through 2000, were the heyday of the internet as its reach and application exploded, eventually leading to the infamous ‘tech bubble’ of 2000 and 2001.
The Spectrum’s article seems to have missed this one completely. They do put the DSL modem from Amati on the list of the top 25 and also recognize the 802.11b WLAN chip from Lucent when the list is expanded to 40. But these chips succeeded only because the basic architecture of the internet was established. These chips then enabled broadband application, albeit opening up a significant new world of applications and impact, but the tale was told in 1994 with V.34 and Netscape. I therefore submit, the RC336 modem chip from Rockwell as one of the top “Earth-shaking” chips of all time.
My second submission to this list is the C50 from TI. The C50 from TI was the follow-on implementation from their seminal fixed-point DSP the C25. The C50 built on the C25′s instruction set but was implemented in a low-power architecture specifically for digital cellular applications. The C50 became the heart of a large array of cell phones that took full advantage of the GSM systems launched in Europe. The digital cellular system combined with the low-power features of the C50 enabled more compact handsets with significantly longer battery life than any previous analog implementation. It was these breakthroughs in size and usability that made cellular phones a technology that was easy to adopt and the numbers quickly showed it. Again, it was a core chip implementation that enabled communication to the masses.
I again commend Spectrum for its article and very much enjoyed the perspective on history. It missed the mark on communication chips, however, and the V.34 modem and the C50 have to be considered on the list. The argument could have been made on commercial significance alone. One of my favorite questions is to ask is to name “billion dollar chips”, chip designs that have generated $1B of revenue in a year. It’s a short list: there’s memory chips, there’s each generation of the x86, there’s the 68000 from Motorola and then …
… there’s the V.34 modem from Rockwell and the C50 from TI. The first three (or their precursors) are all part of the Spectrum article. The last two belong there as well.
