HSP48901 Data Sheet May 1999 File Number 2459.5 3 x 3 Image Filter 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 pr
