Embedded processor economics

As of 2009, more CPUs are produced using the ARM architecture instruction set than any other 32-bit instruction set. The ARM architecture and the first ARM chip were designed in about one and a half years and 5 man years of work time.[1]
The 32-bit Parallax Propeller microcontroller architecture and the first chip were designed by two people in about 10 man years of work time.[2]
It is believed[weasel words] that the 8-bit AVR architecture and first AVR microcontroller was conceived and designed by two students at the Norwegian Institute of Technology.
The 8-bit 6502 architecture and the first 6502 chip were designed in 13 months by a group of about 9 people.[3]
