PDSP1601 MC PDSP1601 MC ALU and Barrel Shifter Supersedes April 1993 version, DS3763 - 1.1 DS3763 - 2.1 November 1998 The PDSP1601 is a high performance 16-bit arithmetic logic unit with an independent on-chip 16-bit barrel shifter.

The PDSP1601 supports Multicycle multiprecision operation.

This allows a single device to operate at 10MHz for 16-bit-bit-fields, 5MHz for 32-bit fields and 2.5MHz for 64-bit fields.

The PDSP1601 can also be cascaded to produce wider words at the 10MHz rate using
