Document Table of Contents Setting and Changing FIR Filter Coefficients at Runtime in DSP Builder


  1. Set the base address of the memory-mapped coefficients with the Base address parameter.
  2. Set the filter coefficients by entering a Simulink fixed-point array into the Coefficients parameter.
  3. Generate a vector of coefficients either by entering an array of numbers, or using one of the many MATLAB functions to build the required coefficients.
  4. Update the parameters through a processor interface during run time using the BusStimulus block. Alternatively, update the parameters from you model by exposing hidden processor interface ports (turn on Expose Bus Ports).
