HSP48908
Two Dimensional Convolver
The Intersil HSP48908 is a high speed Two Dimensional
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 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 HSP48908s. 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 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.
