Data Sheet May 1999
Two Dimensional Convolver
The Intersil HSP48908/883 is a high speed TwoDimensional
Convolver which provides a single chip implementation of a
video data rate 3 x 3 kernel convolution on two dimensional
data. It eliminates the need for external data storage through
the use of the on-chip row buffers which are programmable
for row lengths up to 1024 pixels.
There are internal register banks for storing two independent
3 x 3 filter kernels, thus, facilitating the implementation of
adaptive filters and multiple filter operations on the same
data. The pixel data path also includes an on-chip ALU for
performing real-time arithmetic and logical pixel point
operations.
Data is provided to the HSP48908/883 in a raster scan
noninterlaced fashion, and is internally buffered on images
up to 1024 pixels wide for the 3 x 3 convolution operation.
Images with larger rows and convolution with larger kernel
sizes can be accommodated by using external row buffers
and/or multiple HSP48908/883s. Coefficient and pixel input
data are 8-bit signed or unsigned integers, and the 20-bit
convolver output guarantees no overflow for kernel sizes up
to 4 x 4. Larger kernel sizes can be implemented however,
since the filter coefficients will normally be less than their
maximum 8-bit values.
The HSP48908/883 is manufactured using an advanced
CMOS process, and is a low power fully static design. The
configuration of the device is controlled through a standard
microprocessor interface and all inputs/outputs are TTL
compatible.
