Abstract

The authors describe a compact VLSI implementation of fast pipelined two-dimensional FIR filters. A polyphase architecture is presented. The filter bank makes special use of coefficients which are in powers-of-two. This leads to an interest scheme where only shift and add operations are compared. A novel design strategy has been used to speed up the algorithm, as well as a novel adder. Internally, the speed achieved is around 200 MHz

Digital television

Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV.

Filter bank

In signal processing, a filter bank (or filterbank) is an array of bandpass filters that separates the input signal into multiple components, each one carrying a single frequency sub-band of the original signal. One application of a filter bank is a graphic equalizer, which can attenuate the components differently and recombine them into a modified version of the original signal.

High-definition television

High-definition television (HD or HDTV) describes a television system which provides a substantially higher than the previous generation of technologies. The term has been used since 1936; in more recent times, it refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV. It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television and Blu-ray Discs.
