• How to prepare ADC data for Q31_t CMSIS DSP functions?
    Hi to you all, I've another post on the forum (here's the link Process ADC data, moved by DMA, using CMSIS DSP: what's the right way? ), but since I think I made some small steps forward I felt I could...
  • RFFT CMSIS-DSP - Fluctuating index
    I am using the Cortex M4 with CMSIS 5.4.0 DSP library. I'm using the arm_rfft_f32() function and the max_arm_f32() function to compute the maximum frequency bin of injected pure sine wave with an external...
  • ARM DSP is the way to go – An intern’s perspective
    I’ve been interning at ARM for the last two months as a summer student and spent a fair amount of time looking into the Digital Signal Processing (DSP) market and how it relates to ARM. DSP is used...
  • Cortex M7 DSP moving average UMAAL
    Hello, I am looking to do a moving average function using DSP instructions of ARM Cortex M7. Unfortunately I couldn't find a direct example. My goal is to have variables for - the sum - the new...
  • CMSIS-DSP on ARMv8-m
    Hi, I'm reading through the sources of CMSIS-DSP and came across the following question: The define of "ARM_MATH_DSP" is only set if the target architecture is "ARM_ARCH_7EM". Does this mean, that all...
