hi
anybody knows about what is the xact functional difference between ARM and intel pentium 4 processors ?
why we go for ARm processors ?

thanks a lot

ARM is a RISC processor while Penitum is of CISC architecture.

RISC --> Reduced Instruction set computing ... Complex operations (like MUL )are implemented in software by a series of small hardware operations(Like add)
CISC--> this architecture possess hardware for doing complex operations .

Search google or read any Comp Arch book for difference between RISC and CISC

Petium 4 uses much more power than ARM, I guess that's the main reason especially for battery powered devices.
The price and size could be other factors.

Re: related ARM processors

hi recently one article i studied that
Intel started to apply many of the RISC principles to their CISC microprocessors in the 1990s. For example, the PentiumPro processor has special functional units which crack the majority of the CISC instructions into simpler RISC operations. Internally, the PentiumPro and descendant processors are RISC machines.

is it sure ? then what is difference bet ARm and intel

The ARM is a embedding CPU.
