Chapter 19: Digital signal processing on the cortex-M33 processor
Abstract
This chapter covers a range of topics relating to the application of digital signal processing (DSP) for the Cortex-M33 processor, e.g., the data formats used for signal processing, DSP instruction set features, the handling of overflow in data processing, etc. Using a number of examples, including dot product, biquad filter, the finite impulse response (FIR) filter and fast Fourier transform (FFT), various optimization techniques are demonstrated.
