FPGA based video signal decimators for sample rate reduction from 27/28.64 MHz to 13.5/14.32 MHz

Living, J. and Al-Hashimi, B.M. (1999) FPGA based video signal decimators for sample rate reduction from 27/28.64 MHz to 13.5/14.32 MHz , pp. 38-42.

This paper describes the design and implementation of FPGA based decimator for 2:1 oversampled video signals. The maximum input data rate to be accommodated is 28.64Ms.s-1 for composite (YUV) signals while the most critical frequency response is defined by the CCIR 601 specification for luminance (Y) signals. An ossociated constant group delay characteristic is readilyb achieved by FIR filtering, leading to use of a polyphase network for decimation. The all-pass filters in the polyphase are realised using a distributed arithmetic architecture converted for digit-serial operation and a modular, resource efficent connection scheme for higher-order filters is considered. The decimators have been implemented using Xilinx XC4000E series FPGAs with -3 speed grade parts achieving sample processing rates of 30Ms.s[1, clearly meeting the required performance.
