Histogrammer/Accumulating Buffer
The Intersil HSP48410/883 is an 84 lead Histogrammer IC
int.ended for use in image and signal analysis. The on board
memory is configured as 1024 x 24 array. This translates to
a pixel resolution of 10 bits and an image size of 4k x 4k with
no possibility of overflow.
In addition to 4-Histogramming, the HSP48410 can generate
and store the Cumulative Distribution Function for use in
Histogram Equalization Applications. Other capabilities of
the HSP48410 include: Bin Accumulation, Look Up Table,
24-bit Delay Memory, and Delay and Subtract Mode.
A flash clear pin is available in all modes of operation and
performs a single cycle reset on all locations of the internal
memory array and all internal data paths.
The HSP48410 includes a fully asynchronous interface
which provides a means for communications with a host,
such as a microprocessor. The interface includes dedicated
Read/Write pins and an address port which are
asynchronous to the system clock. This allows random
access of the Histogram Memory Array for analysis or
conditioning of the stored data.
