• Loop unrolling on Cortex-M3 vs. Cortex-M0

    Indu Girish
    Indu Girish

    In the DSP lib files like arm_conv_f32, arm_fir_f32, the algorithm implementation in Cortex-M3/M4 and in Cortex-M0 is different. i.e., loop unrolling is used in M3/M4 and it is not used in M0.

    Pls tell me the reason behind it. Is there any advantage of…

    In this blog I take a close look at the code size of ARM’s Thumb instruction set against the microMIPS32 instruction set, as used in the microAptiv processor family.  More specifically I look at recent claims that microMIPS32 has 17%-30% better code…

    I saw what looks like the start of a series of short videos on the ARMflix YouTube channel.

    Of course, it doesn't go into much details, but I thought it was a simple way to discover the series.

    As they come up, anyone please feel free to edit this…
