ShiftFract32

Overview

Arithmetic shift of integer or fractional data

Discussion

THIS MODULE IS DEPRECATED AND NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE ShiftBits MODULE INSTEAD.

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.
