PDSP16116
16 X 16 Bit Complex Multiplier
DS3707 - 5.3 October 1997
The PDSP16116 contains four 16316 array multipliers, two
32-bit adder/subtractors and all the control logic required to sup-
port Block Floating Point Arithmetic as used in FFT applications.
The PDSP16116A variant will multiply two complex (16116)
bit words every 50ns and can be configured to output the com-
plete complex (32132) bit result within a single cycle. The data
format is fractional two’s complement.
In combination with a PDSP16318A, the PDSP16116A forms
a two-chip 20MHz complex multiplier accumulator with 20-bit
accumulator registers and output shifters. The PDSP16116A in
combination with two PDSP16318As and two PDSP1601As
forms a complete 20MHz Radix 2 DIT FFT butterfly solution
which fully supports block floating point arithmetic. The
PDSP16116 has an extremely high throughput that is suited to
recursive algorithms as all calculations are performed with a
single pipeline delay (two cycle fall-through).
