PDSP16116

16 X 16 Bit Complex Multiplier

Supersedes October 1996 version, DS3707 - 4.2

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 PointArithmetic as used in FFT applications.

The PDSP16116Avariant 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 PDSP16116Aforms

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).
