@brief Instance structure for the Q15 sparse FIR filter.

Fields

numTaps: u16

< number of coefficients in the filter.

stateIndex: u16

< state buffer index. Points to the oldest sample in the state buffer.

pState: *mut q15_t

< points to the state buffer array. The array is of length maxDelay+blockSize-1.

pCoeffs: *const q15_t

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

maxDelay: u16

< maximum offset specified by the pTapDelay array.

pTapDelay: *mut i32

< points to the array of delay values. The array is of length numTaps.
