Abstract

The problem of generalized 2D FIR filtering for large filter kernel sizes can be computationally prohibitive when required in real-time, such as with video applications. In this paper, we describe architectures and design methods for generalized 2D FIR filtering employing LOGIC Devices´ LF33xx (HV filter) family of devices. The LF33xx family of devices is designed to perform dimensionally separate filtering (row/column) along orthogonal axes (horizontal direction and vertical direction for video applications). Additionally, we will briefly review 2D filter design and kernel separability theory
