PDSP16510A

Stand Alone FFT Processor

Supersedes version in December 1993 Digital Video & DSP IC Handbook, HB3923-1

DS3475 - 4.4 May 1996

The PDSP16510 performs Forward or Inverse Fast

Fourier Transforms on complex or real data sets containing up

to 1024 points. Data and coefficients are each represented by

16 bits, with block floating point arithmetic for increased

dynamic range.

An internal RAM is provided which can hold up to 1024

complex data points. This removes the memory transfer

bottleneck, inherent in building block solutions. Its organisa-

tion allows the PDSP16510 to simultaneously input new data,

transform data stored in the RAM, and to output previous

results. No external buffering is needed for transforms con-

taining up to 256 points, and the PDSP16510 can be directly

connected to an A/D converter to perform continuous trans-

forms. The user can choose to overlap data blocks by either

0%, 50%, or 75%. Inputs and outputs are synchronous to the

40MHz system clock used for internal operations.

BUFFER

A 1024 point complex transform can be completed in

some 98µs, which is equivalent to throughput rates of 450

million operations per second. Multiple devices can be con-

nected in parallel in order to increase the sampling rate up to

the 40MHz system clock. Six devices are needed to give the

maximum performance with 1024 point transforms.

Either a Hamming or a Blackman-Harris window operator

can be internally applied to the incoming real or complex data.

The latter gives 67dB side lobe attenuation. The operator

values are calculated internally and do not require an external

ROM nor do they incur any time penalty.

FEATURES

Completely self contained FFT Processor

Internal RAM supports up to1024 complex points

The device outputs the real and imaginary components of

the frequency bins. These can be directly connected to the

PDSP16330 in order to produce magnitude and phase values

from the complex data.
