... LINE BUFFER 3K LINE BUFFER Horizontal / Vertical Digital Image Filter Horizontal / Vertical Digital Image Filter DESCRIPTION The LF3310 is a two-dimensional digital image filter capable of filtering data at real-time video rates. The device con- tains both a horizontal and a vertical filter which may be cascaded or used concurrently for two-dimensional filter- ing ...

... LF Interface section. TM Horizontal Select The word width of the horizontal 9 LF3310 filter output is 32-bits. However, only 12-bits may be sent to the filter output. The horizontal filter select circuitry determines which 12-bits are passed (see Table 1). The horizontal select registers control the horizontal select circuitry ...
