Overview

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 support 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 complete 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).
