Advance Information

DS4548

ISSUE 4.0

August 1998

The VP16256 contains sixteen multiplier - accumulators, which

canbemulticycledtoprovidefrom16to128stagesofdigitalfiltering.

Input data and coefficients are both represented by 16-bit two’s

complementnumberswithcoefficientsconvertedinternallyto12bits

and the results being accumulated up to 32 bits.

PIN 1

In16-tapmodethedevicesamplesdataatthesystemclockrate

ofupto40MHz. Ifalowersamplerateisacceptablethenthenumber

ofstagescanbeincreasedinpowersoftwouptoamaximumof128.

Each time the number of stages is doubled, the sample clock rate

mustbehalvedwithrespecttothesystemclock. With128stagesthe

sample clock is therefore one eighth of the system clock.

In all speed modes devices can be cascaded to provide filters of

anylength,onlylimitedbythepossibilityofaccumulatoroverflow.The

32-bit results are passed between cascaded devices without any

intermediate scaling and subsequent loss of precision.

PIN 1 IDENT

208

The device can be configured as either one long filter or two

separate filters with half the number of taps in each. Both networks

can have independent inputs and outputs.

Bothsingleandcascadeddevicescanbeoperatedindecimate-

by-two mode. The output rate is then half the input rate, but twice the

numberofstagesarepossibleatagivensamplerate.Asingledevice

witha40MHzclockwouldthen,forexample,providea128-stagelow

pass filter, with a 10MHz input rate and 5MHz output rate.

Coefficients are stored internally and can be down loaded from

a host system or an EPROM. The latter requires no additional

support, and is used in stand alone applications. A full set of

coefficientsisthenautomaticallyloadedatpoweron,orattherequest

of the system. A single EPROM can be used to provide coefficients

for up to 16 devices.
