DESCRIPTION  
Interleave/ Decimation Registers (I/ D  
Registers) allow interleaved data to be  
fed directly into the device and filtered  
without separating the data into  
The LF3320 filters digital images in the  
horizontal dimension at real-time  
video rates. The input and coefficient  
data are both 12 bits and in twos

sixteen data sets interleaved together.  
The I/ D Registers and on-chip accu-  
mulators facilitate using decimation to  
increase the number of filter taps.  
The LF3320 is designed to take  
advantage ofsymmetriccoefficient  
sets. When symmetric coefficient sets  
are used, the device can be configured  
as a single 32-tap FIR filter or as two  
separate 16-tap FIR filters.
