Overview
LF48410 DEVICES INCORPORATED 1024 x 24-bit Video Histogrammer LF48410 DEVICES INCORPORATED 1024 x 24-bit Video Histogrammer DESCRIPTION The LF48410 is capable of generating histograms and Cumulative Distribution Functions of video images.
It may also be used as a look up table, a bin accumulator, a delay memory (delay and subtract also possible), or a single port RAM.
The on-chip 1024 x 24-bit memory array facilitates histograms of images up to 4K x 4K pixels with a 10-bit pixel resolution.
Once the histogram of a video image is stored in the memory array, the Cumulative Distribution Function can be calculated by putting the device in Histogram Accumulate Mode.
Transformation functions can be performed on pixel values when the device is in Look Up Table Mode.
If the Cumulative Distribution Function is the desired transformation function, the LF48410 can calculate it and have it available for Look Up Table Mode.
When the device is in Delay Memory Mode, it functions as a video row buffer.
In this mode, the LF48410 can buffer video lines as long as 1029 pixels.
The device can also function as an asynchronous single port RAM.
During asynchronous modes, the device can be configured as a 1024 x 24, 1024 x 16, or 1024 x 8-bit RAM.
A Flash Clear function is provided which sets all memory array locations and data path registers to “0”.
