Two Dimensional Convolver

Features

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.

• Single Chip 3 x 3 Kernel Convolution

• Programmable On-Chip Row Buffers

• DC to 32MHz Clock Rate

• Cascadable for Larger Kernels and Images

• On-Chip 8-Bit ALU

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.

• Dual Coefﬁcient Mask Registers, Switchable in a

Single Clock Cycle

• 8-Bit Signed or Unsigned Input and Coefﬁcient Data

• 20-Bit Extended Precision Output

• Standard µP Interface

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.

• Low Power CMOS

Applications

• Image Filtering

• Edge Detection

• Adaptive Filtering

• Real Time Video Filter

Ordering Information

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.
