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 processed within the required frame time for real-time video. Data is provided to the HSP48901 through the use of programmable data buffers such as the HSP9500 or any other Programmable Shift Register.
