HSP48410
Histogrammer/Accumulating Buffer
The Intersil HSP48410 is an 84 lead Histogrammer IC
intended 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 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.
