Unsatified with the processors then available on the market, the Acorn engineers decided to make the leap to creating their own 32-bit microprocessor. ARM1 was released in 1985.
They called it the Acorn RISC Machine, or ARM.
In 1990, Acorn spun off its ARM division, and the ARM architecture went on to become the dominant 32-bit processor for embedded application: More than 10 billion ARM cores have been used.
Today that ARM division is big. In electronics design IP industry still has only one big company: ARM isdominating mobile phone circuits and dominates nearly half of IP sales (ARM’s sales were nearly $ 1.65 billion, or 48.4 percent of the total market).
