Field Documentation

◆ M

uint8_t riscv_fir_decimate_instance_q31::M

decimation factor.

◆ numTaps

uint16_t riscv_fir_decimate_instance_q31::numTaps

number of coefficients in the filter.

◆ pCoeffs

const q31_t* riscv_fir_decimate_instance_q31::pCoeffs

points to the coefficient array. The array is of length numTaps.

◆ pState

q31_t* riscv_fir_decimate_instance_q31::pState

points to the state variable array. The array is of length numTaps+blockSize-1.
