Data Fields | |
uint16_t | numTaps |
uint16_t | stateIndex |
q31_t * | pState |
const q31_t * | pCoeffs |
uint16_t | maxDelay |
int32_t * | pTapDelay |
uint16_t maxDelay |
maximum offset specified by the pTapDelay array.
uint16_t numTaps |
number of coefficients in the filter.
const q31_t* pCoeffs |
points to the coefficient array. The array is of length numTaps.
q31_t* pState |
points to the state buffer array. The array is of length maxDelay+blockSize-1.
int32_t* pTapDelay |
points to the array of delay values. The array is of length numTaps.
uint16_t stateIndex |
state buffer index. Points to the oldest sample in the state buffer.
