• CMSIS DSP FIR filter for continous real signal
    Hello, DSP concept guys say, that it's time to use ARM Cortex-M microcontrollers for embedded DSP systems, so I looked at CMSIS library of filtering functions, and found that it is of block type. As you...
  • CMSIS DSP - FIR decimation
    Hi, I am trying to implement FIR decimation on PDM input. Which FIR decimator function should I use? I am now trying to implement arm_fir_decimate_fast_q15 since I need to feed the output (hopefully PCM...
  • STM32F427ZG and CMSIS FIR Filters
    I am using STM32F427ZG and have a query about the CMSIS FIR Filter functions. We require highest possible speed in a 16 bit environment. I have been comparing speeds for the q15,q31 and float32 FIR...
  • Realtime CMSIS FIR Filter Issue
    Hi everyone, I'm trying to implement a realtime lowpass FIR filter using the CMSIS library. I'm essentially following their example here: http://www.keil.com/pack/doc/CMSIS/DSP/html/group__FIRLPF...
  • STM32 real time FIR filter from ADC samples
    Hello, I have a Nucleo-L476RG board and I'm trying to make a lowpass filter with the FIR function (using cmsis libraries) to filter the samples I get from the ADC in realtime. Then I'd like to get the...
