PDSP160P1D/SPPD160S1/PPD1S6P016101AA
ALU and Barrel Shifter
Supersedes version DS3705 - 2.3 September 1996
DS3705 - 3.0 November 1998
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 and 5MHz for 64-bit fields.
The PDSP1601 can also be cascaded to produce wider words
at the 20MHz rate using the Carry Out and Carry In pins. The
Barrel Shifter is also capable of extension, for example the
PDSP1601 can used to select a 16-bit field from a 32-bit input
in 100ns.
