    Is it possible to integrate ARM 5 toolchain with armcc compiler in eclipse?

    I have installed the ARM 5 compiler, but in c/c++ build > tool chain editor I can only select a gcc based toolchain.

    Thank you for feedback.

    Hello everybody,

    im using the Math.h file to do a rfft with 1024 points und q15 datatype.

    So far everything works fine, and I get good results. It needs a computation time of ~720us on my CortexM4 @100Mhz.

    This is very Impressive, but to long for my application…

    Hello!

    I'm using a Zybo board with a dual-core ARM Cortex-A9 processor and I'm trying to read (and then write) the registers of the processor. How can I read these values into variables in C code?

    hi all,

    I'm used to use microchip controllers (Professional software engineer), but because I need higher calculation speed, I have to move to arm processors.

    For that reason I'd like to start with a starter kit.

    I'd like to experiment with Ethernet…
