Editing Acorn Archimedes A440 (section)

=== Processor and Architecture ===
The A440 used the ARM2 processor running at 8 MHz, providing 32-bit processing with 26-bit addressing . The system was stated as running at 4.5+ MIPS, with some claims of 18 MIPS during tests . The performance increase was due to the fundamental architecture change from the 6502 models, with Acorn designing the ARM processor inspired by RISC work at Berkeley and Stanford Universities .
