| > Before ARM the m68k was possibly the most deployed processor architecture in history My money would be on something smaller such as the 8051 (https://en.wikipedia.org/wiki/Intel_MCS-51) Also, between m68k and ARM there was PowerPC. It got used a lot in embedded systems. Because “the newer the car, the more microprocessors it has”, chances are it got used more than m68k. FWIW, Google’s AI gives me: - for the m68k: “industry analysis and historical data indicate that hundreds of millions of units were produced across the architecture's lifespan” - for PowerPC: “By 2008, Freescale Semiconductor had already shipped over 100 million Power Architecture-based MCUs for automotive powertrain management alone. Hundreds of millions more have since been produced for networking, industrial automation, and aerospace applications.” - for the 8051: “according to industry accounts and semiconductor historians, the cumulative production of 8051-based microcontrollers is estimated to be on the order of billions to tens of billions of units” |
Also MIPS. It was VERY popular in embedded. Also Sony’s PS1 and PS2.
