ARM Architecture in naive terms.
ARM is 32 bit architecture. It is based on the RISC cpu design. It means if has fewer instructions set.
Fewer instruction set may mean
a) Limited functionality.
b) Less power demand. Using the RISC approach, the ARM processor requires only 35,000 transistors, compared to the millions in many conventional processor chips, resulting in a much lower power usage
Normally a) above is okay, as in small embedded devices need 'not' to perform zillions of operation as required by the Home PC. But, by design ARM also has improved data store and transfer capability during various calculations. This makes processing more efficient
About b) above, Ah, thats what we need for hand held devices. Long battery backup.
