Detailed Description

The tcFIRFilter_MCBD_SIFO class provides for optimized processing of multi-channel block decimating (MCBD) FIR processing, using Short Inputs and yeilding Floating point Outputs (SIFO).

Constructor & Destructor Documentation

tcFIRFilter_MCBD_SIFO::tcFIRFilter_MCBD_SIFO	(	short *	coefs,
		int	ntaps,
		int	NumChannels = 1,
		int	ChannelStride = 1,
		int	Decimation = 1
	)

FIR Filter, Multi-Channel Block Decimate Short Input Float Output Class constructor.

Parameters:

[in]	coefs	- pointer to reference weights, must be managed by application code and should be allocated in cache memory if at all possible.
[in]	ntaps	- number of reference weights in the filter. Must be divisible by 4 and >= 20.
[in]	NumChannels	- number of channels multiplexed in the data stream
[in]	ChannelStride	- spacing (in words) between two packed channels (should be 1)
[in]	Decimation	- block decimation factor, must be >= 1

Destructor. Note: the coefficient pointer is managed by the application so no cleanup should be performed here.
