Two Dimensional Convolver

Features

The Intersil HSP48908/883 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.

• This Circuit is Processed in Accordance to MIL-STD-883

and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

• Single Chip 3 x 3 Kernel Convolution

• Programmable On-Chip Row Buffers

• DC to 27MHz Clock Rate

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.

• Cascadable for Larger Kernels and Images

• On-Chip 8-Bit ALU

• 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 HSP48908/883 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.

Applications

• Image Filtering

• Edge Detection

• Adaptive Filtering

• Real Time Video Filter

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.
