The data format is fractional two's complement. The PDSP16116/A contains four 16 x 16 Array Multipliers, two 32 bit Adder/Subtractors and all the control logic required to support Block Floating Point Arithmetic as used in FFT applications. In combination with a PDSP16318, the PDSP16116A forms a two chip 10MHz Complex Multiplier Accumulator with 20 bit accumulator registers and output shifters. The PDSP16116 in combination with two PDSP16318s and two PDSP1601s forms a complete 10MHz Radix 2 DIT FFT Butterfly solution which fully supports Block Floating Point Arithmetic. The PDSP16116/A 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).
