LOGIC Devices Incorporated LF3310

The LF3310 is a two-dimensional digital image filter capable of filtering data at real-time video rates. The device contains both a horizontal and a vertical filter which may be cascaded or used concurrently for two-dimensional filtering. The input, coefficient, and output data are all 12-bits and in two’s complement format.

DESCRIPTION

The horizontal filter is designed to take advantage of symmetric coefficient sets. When symmetric coefficient sets are used, the horizontal filter can be configured as a 16-tap FIR filter. When asymmetric coefficient sets are used, it can be configured as an 8-tap FIR filter. The vertical filter is an 8-tap FIR filter with all required line buffers contained on-chip. The line buffers can store video lines with lengths from 4 to 3076 pixels. Horizontal filter Interleave/Decimation Registers (I/D Registers) and the vertical filter line buffers allow interleaved data to be fed directly into the device and filtered without separating the data into individual data streams. The horizontal filter can handle a maximum of sixteen data sets interleaved together. The vertical filter can handle interleaved video lines which contain 3076 or less data values. The I/D Registers and horizontal accumulator facilitate using decimation to increase the number of filter taps in the horizontal filter.
