Overview

Arithmetic shift of integer or fractional data

Discussion

Computes the arithmetic shift of a multichannel signal. The module supports fractional, and integer signals. numBits specifies the number of bit(between -31 and +31) positions to be shifted. If numBits is positive, left shift will be performed. If numBits is negative, right shift will be performed. Values outside of the allowable range are clipped. Negative values are sign extended when shifted left.

Type Definition

typedef struct _ModuleShiftFract32
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 numBits;                                // Integer value that specifies the number of bits to shift the input.
} ModuleShiftFract32Class;
