LSH32 DEVICES INCORPORATED 32-bit Cascadable Barrel Shifter LSH32 DEVICES INCORPORATED 32-bit Cascadable Barrel Shifter 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. SHIFT ARRAY The 32 inputs to the LSH32 are applied to a 32-bit shift array. The 32 outputs of this array are multiplexed down to 16 lines for presentation at the device outputs.
