Overview
- See also: arm/history and ARM's History
Introduced in 1986, the ARM2 is a reimplementation of the ARM1 on a smaller process along with the addition of a number of additional enhancements. The ARM2 was capable of exceeding 10 MIPS when not bottlenecked by memory.
Process Technology
- See also: 2 µm process
ARM2 chips were manufactured by VLSI Technology and Sanyo on a 2 µm double-level metal CMOS process.
