Hello,
I have been using CMSIS library for implementation of DSP functions in ARM, however, CMSIS have very limited DSP functions. Although GNU has many DSP functions which CMSIS do not, It only have floating point implementation. I am trying…

FIR decimator filter
Hello there, I have a question regarding the CMSIS DSP library function arm_fir_decimate_X.
So for example if I have an ADC which is sampling at 5250 kHz and I want to create a filter using the decimate function, do I have to run the sampled signal through…

CMSIS DSP Library FIR filter in realtime application
Hello,
I am new to DSP things and I just built my first test project. This is a low pass filter with an order of 31, so 32 coefficients. Also I have an input buffer of 32 values that I designed as a ring buffer. With these I programmed a standard FIR…
