PDSP16318/PDSP16318A
Complex Accumulator
Advance Information
The PDSP16318/A contains two independent 20-bit
Adder/Subtractors combined with accumulator registers and
shift structures. The four port architecture permits full 20MHz
throughout in FFT and filter applications.
Two PDSP16318As combined with a single PDSP16112A
Complex Multiplier provide a complete arithmetic solution for
a Radix 2 DIT FFT Butterfly. A new complex Butterfly result
can be generated every 50ns allowing 1K complex FFTs to be
executed in 256
μ
s.
