PDSP1601GC1R fiche technique
Supersedes April 1993 version, DS3763 - 1.1
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 the Carry Out and Carry In pins.
The Barrel Shifter is capable of extension, for example the
PDSP1601 can used to select a 16-bit field from a 32-bit input
in 100ns.
