A new time distributed DCT architecture for MPEG-4 hardware reference model

This paper presents the design of a new time distributed architecture (TDA) which outlines the architecture (ISO/IEC JTC1/SC29/WG11 MPEG2002/M8565) submitted to MPEG4 Part9 committee and included in the ISO/IEC JTC1/SC29/WG11 MPEG2002/9115N document. The proposed TDA optimizes the two-dimensional discrete cosine transform (2-D-DCT) architecture performance. It uses a time distribution mechanism to exploit the computational redundancy within the inner product computation module. The application specific requirements of input, output and coefficients word length are met by scheduling the input data. The coefficient matrix uses linear mappings to assign necessary computation to processor elements in both space and time domains. The performance analysis shows performance savings in excess of 96% as compared to the direct implementation and more than 71% as compared to other optimized application specific architectures for DCT.

Avoid these advertising mistakes at all costs!

People have taken a number of approaches trying to do their own advertising ranging from silly all the way to insulting. These people choose there approach for various reasons. Some were ignorant about advertising and marketing while others were acting on incorrect information – usually in the form of cliches such as “sex sells.” If you’re in doubt, I can assure you that unless your business is in Nevada, sex does not sell. If you’re going to handle your own advertising, here are a few things to avoid:

Pictures that have nothing to do with your product or service – If your company is in the carpet cleaning business there is no reason to have a picture of a baby. No one is going to say “What a cute baby, I think I want this company to clean my carpets.” The same goes for pictures of sexy people (male or female) in provocative poses and little clothing.

Cheesy headlines – I actually saw an ad with a headline that said “We might be able to afford a bigger ad if you’d buy something from us.” Yes, this will probably get someone’s attention, but do you want to be remembered as the company that is having financial problems?

Illegible fonts – Most people will not take the time to decipher your ad when it is written in brush script, in which case, even the most persuasive copy is rendered useless. You want to use simple, clean fonts for headlines and body copy. Save the artistic fonts for accents and things of that nature.
