FEATURES
DESCRIPTION
DEVICES INCORPORATED
The
LF48410
is capable of generating
histograms and Cumulative Distribu-
tion 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 func-
tion, 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”.
