Detailed Description

Instance structure for the Q15 LMS filter.

Field Documentation

mu

q15_t riscv_lms_instance_q15::mu

step size that controls filter coefficient updates.

numTaps

uint16_t riscv_lms_instance_q15::numTaps

number of coefficients in the filter.

pCoeffs

q15_t* riscv_lms_instance_q15::pCoeffs

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

postShift

uint32_t riscv_lms_instance_q15::postShift

bit shift applied to coefficients.

pState

q15_t* riscv_lms_instance_q15::pState

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