3 x 3 Image Filter

Features

The Intersil HSP48901 is a high speed 9-Tap FIR Filter

which utilizes 8-bit wide data and coefficients. It can be

configured as a one-dimensional (1-D) 9-Tap filter for a

variety of signal processing applications, or as a two

dimensional (2-D) filter for image processing. In the 2-D

configuration, the device is ideally suited for implementing 3

x 3 kernel convolution. The 30MHz clock rate allows a large

number of image sizes to be processed within the required

frame time for real-time video.

• DC to 30MHz Clock Rate

• Configurable for 1-D and 2-D Correlation/Convolution

• Dual Coefficient Mask Registers, Switchable in a Single

Clock Cycle

• Two’s Complement or Unsigned 8-Bit Input Data and

Coefficients

• 20-Bit Extended Precision Output

• Standard µP Interface

Data is provided to the HSP48901 through the use of

programmable data buffers such as the HSP9500 or any

other Programmable Shift Register. Coefficient and pixel

input data are 8-bit signed or unsigned integers, and the

20-bit extended output guarantees no overflow will occur

during the filtering operation.

Applications

• Image Filtering

• Edge Detection/Enhancement

• Pattern Matching

• Real Time Video Filters

There are two internal register banks for storing independent

3 x 3 filter kernels, thus, facilitating the implementation of

adaptive filters and multiple filter operations on the same

data.
