LSH32JC32 Datasheet PDF - LOGIC Devices

DESCRIPTION
The LSH32 is a 32-bit high speed shifter designed for use in floating point normalization, word pack/unpack, field extraction, and similar applications. It has 32 data inputs, and 16 output lines. Any shift configuration of the 32 inputs, including circular (barrel) shifting, left shifts with zero fill, and right shift with sign extend are possible. In addition, a built-in priority encoder is provided to aid floating point normalization.
