Data Structures
struct	DSPLIB_cascadeBiquad_InitArgs
	Structure containing the parameters to initialize the kernel. More...

Functions
int32_t	DSPLIB_cascadeBiquad_getHandleSize (DSPLIB_cascadeBiquad_InitArgs *pKerInitArgs)
	This is a query function to calculate the size of internal handle. More...
int32_t	DSPLIB_cascadeBiquad_get_coefficientsBufferSize (uint32_t numStages)
	This is a query function to calculate the sizes of coefficient buffer needed based on the number of stages. More...
DSPLIB_STATUS	DSPLIB_cascadeBiquad_init (DSPLIB_kernelHandle handle, DSPLIB_bufParams2D_t *bufParamsIn, DSPLIB_bufParams1D_t *bufParamsFilterCoeff, DSPLIB_bufParams2D_t *bufParamsFilterVar, DSPLIB_bufParams2D_t *bufParamsOut, DSPLIB_cascadeBiquad_InitArgs *pKerInitArgs)
	This function should be called before the DSPLIB_cascadeBiquad_exec function is called. This function takes care of any one-time operations such as setting up the configuration of required hardware resources such as the MMA accelerator and the streaming engine. The results of these operations are stored in the handle. More...
DSPLIB_STATUS	DSPLIB_cascadeBiquad_init_checkParams (DSPLIB_kernelHandle handle, const DSPLIB_bufParams2D_t *bufParamsIn, const DSPLIB_bufParams1D_t *bufParamsFilterCoeff, const DSPLIB_bufParams2D_t *bufParamsFilterVar, const DSPLIB_bufParams2D_t *bufParamsOut, const DSPLIB_cascadeBiquad_InitArgs *pKerInitArgs)
	This function checks the validity of the parameters passed to DSPLIB_cascadeBiquad_init function. This function is called with the same parameters as the DSPLIB_cascadeBiquad_init, and this function must be called before the DSPLIB_cascadeBiquad_init is called. More...
DSPLIB_STATUS	DSPLIB_cascadeBiquad_exec (DSPLIB_kernelHandle handle, void *restrict pIn, void *restrict pFilterCoeff, void *restrict pFilterVar, void *restrict pOut)
	This function is the main kernel compute function. More...
DSPLIB_STATUS	DSPLIB_cascadeBiquad_exec_checkParams (DSPLIB_kernelHandle handle, const void *restrict pIn, const void *restrict pFilterCoeff, const void *restrict pFilterVar, const void *restrict pOut)
	This function checks the validity of the parameters passed to DSPLIB_cascadeBiquad_exec function. This function is called with the same parameters as the DSPLIB_cascadeBiquad_exec, and this function must be called before the DSPLIB_cascadeBiquad_exec is called. More...
void	DSPLIB_cascadeBiquad_perfEst (DSPLIB_kernelHandle handle, const DSPLIB_bufParams2D_t *bufParamsIn, const DSPLIB_bufParams1D_t *bufParamsFilterCoeff, const DSPLIB_bufParams2D_t *bufParamsFilterVar, const DSPLIB_bufParams2D_t *bufParamsOut, uint64_t *archCycles, uint64_t *estCycles)
	This is a utility function that gives an estimate of the cycles consumed for the kernel execution. More...
