4. Advanced/Acorn RISCMachines
and
Reduced Instruction Set Computing
• Tim’s line numbering!
• An alternative to CISC (x86) processors
• Acorn Archimedes the first commercial
computer designed to specifically use an ARM
processor
• Developed by Acorn in partnership with VLSI
• Acorn and Apple joined forces to develop newer
versions of the ARM processor ending up the
creation of ARM Ltd
• ARM processors are very popular as they are
inexpensive and offer great performance with
minimal power usage

5. RISC OS

6. What happened to the
Archimedes?
• In the mid 90’s schools started to look to
windows based PC’s
• Tesco’s computers for schools scheme
signed a deal with another British
computer manufacturer RM instead of
Acorn
• As a company Acorn fell on hard times and
started focusing on other technologies such
as set top boxes
• Acorn were developing a new RISC
computer called Phoebe, but was cancelled
due to a company re-structure
(Flibble, 2011)
