    Re: what is the difference between ARM and PIC processor?

    Below is a list. I have compiled it in December 2008. Obviously, it's not a complete list, and it's merely a single opinion.

    Pros and Cons of ARMs (compared to PIC18)

    Pro:
    • Ample resources (ROM, RAM)
    • Faster program execution.
    • More sophisticated interrupt architecture
    • Exceptions
    • C++ compilers, which might speed-up development and facilitate code reuse
    • JTAG
    • Many silicon vendors
    • Many flavors

    Con:
    • Smaller mind share
    • Lack of small device (the smallest one is 48-QFP)
    • Larger amount of necessary external hardware

    Re: what is the difference between ARM and PIC processor?

    Hi,

    Comparing a 32 bits ARM with an 8 bits PIC18 is like comparing a bicycle with a truck...

    A fair comparison is comparing an ARM with a PIC32.

    Actually there is a benchmark done by an independant source called coremark.
    Just select NXP (Cortex M3 core) & Microchip :
    http://www.coremark.org/benchmark/in...p?pg=benchmark

    You'll see that the result is that the 80MHz PIC32 scores higher than the 100MHz NXP device...

    If you want to get started : http://www.microchip.com/PIC32

    regards
