After examining the files in depth, I realized I need some help understanding core concepts in FPGA programming:
In "axi_fir_filter.v" there is a parameter named "USE_EMBEDDED_REGS_COEFFS", and explained in comment: " Reduce register usage by only using embedded registers in DSP slices". - What is the actual difference between registers and embedded registers? - Does the implementation of the two only differ in usage of "wire" vs. "reg"?
