10 / 21 page DEVICES INCORPORATED LF3310 Horizontal / Vertical Digital Image Filter 10 Video Imaging Products 11/08/2001-LDS.3310-H changed every clock cycle. This is useful when filtering interleaved data. When loading limit values into the device, the upper limit must be greater than the lower limit. Limit register loading is discussed in the LF InterfaceTM section. Vertical Filter The vertical filter is designed to filter a digital image in the vertical dimen- sion. It is a FIR filter which can be configured to have as many as 8-taps. Line Buffers There are seven on-chip line buffers. The maximum delay length of each line buffer is 3076 cycles and the minimum is 4 cycles. Configuration Register 2 (CR2) determines the delay length of the line buffers. The line buffer length is equal to the value of CR2 plus 4. A value of 0 for CR2 sets the line buffer length to 4. A value of 3072 for CR2 sets the line buffer length to 3076. Any values for CR2 greater than 3072 are not valid. The line buffers have two modes of operation: delay mode and recirculate mode. Bit 0 of Configuration Register 3 determines which mode the line buffers are in. In delay mode, the data input to the line buffer is delayed by an amount determined by CR2. In recirculate mode, the output of the line buffer is routed back to the input of the line buffer allowing the line buffer contents to be read multiple times. Bit 1 of Configuration Register 3 allows the line buffers to be loaded in parallel. When Bit 1 is “1”, the input register (DIN11-0) loads all seven line buffers in parallel. This allows all the line buffers to be preloaded with data in the amount of time it normally takes to load a single line buffer. VSHEN enables or disables the loading of data into the line buffers when the device is in Dimensionally Separate Mode (see the VSHEN section for a full discussion). When in Orthogonal Mode, VSHEN also enables or disables the loading of data into the input register (DIN11-0) and the forward and reverse I/D Registers. It is important to note that in Or- thogonal Mode, either HSHEN or VSHEN can disable the loading of data into the input register (DIN11-0), I/D Registers, and line buffers. Both must be active to enable data loading in Orthogonal Mode. Interleaved Data The vertical filter is capable of handling interleaved data. The number of data sets it can handle is determined by the number of data values contained in a video line. If the interleaved video line has 3076 data values or less, the vertical filter can handle it no matter how many data sets are interleaved together.
