PDSP1601/PDSP1601A ALU and Barrel Shifter Supersedes version DS3705 - 2.3 September 1996 DS3705 - 3.0 November 1998 PDSP1601/PDSP1601A The PDSP1601 is a high performance 16-bit arithmetic logic unit with an independent on-chip 16-bit barrel shifter.

The PDSP1601A has two operating modes giving 20MHz or 10MHz register-to-register transfer rates.

The PDSP1601 supports Multicycle multiprecision operation.

This allows a single device to operate at 20MHz for 16-bit fields, 10MHz for 32-bit fields a
