One of the huge reasons for picking the ARM is that it's very well suited to being integrated into the same chip (...) (18 years ago, 9-Jan-06, to lugnet.robotics)

However, with any ARM7 implementation it can be catered to a specific applications. From the ARM website: (...) (18 years ago, 9-Jan-06, to lugnet.robotics)

CISC instructions often combine data memory references with arithmetic, logical, or brach capabilities. RISC machines do not. (...) (18 years ago, 10-Jan-06, to lugnet.robotics, FTX)
