HSP48410/883

Data Sheet May 1999

Histogrammer/Accumulating Buffer

The Intersil HSP48410/883 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 pixelresolution of 10 bits and an image size of 4k x 4k with no possibility of overﬂow.

In addition to 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.
