16.3.4 DSP On-Chip Library Functions
The DSP library is an easy way to implement DSP functions. It consists of the following
functions:
• FIR1—Finite impulse response 1
• FIR2—Finite impulse response 2
• FIR3—Finite impulse response 3
• FIR5—Finite impulse response 5
• FIR6—Finite impulse response 6
• IIR—Infinite impulse response
• MOD—Modulation
• DEMOD—Demodulation
• LMS1—Least mean squared 1
• LMS2—Least mean squared 2
• WADD—Weighted vector addition
