A FAST PIPELINED IMPLEMENTATION OF TWO DIMENSIONAL INVERSE DISCRETE COSINE TRANSFORMS

Abstract:- The inverse discrete cosine transform (IDCT) is a significant component in todayâ„¢s JPEG and MPEG decoders. Of all the stages in the decoding process of a JPEG file, the IDCT is the most computationally intensive. Hence, we require fast and efficient implementations, either in software or hardware. Numerous individual designs for computing the ID-IDCT have been proposed. Our 2D-IDCT incorporates two of our ID-IDCT cores and a transpose netwo ....etc

Local Area Networks are now being used to transport voice and video traffic together with traditional data traffic that they have already supported. And in the case of voice and video applications, not only is these is a need for more bandwidth, but there is also a need for guaranteed levels of receive because these applications are very sensitive to latency and delay.
Inverse multiplexing can be proved as technology that overcomes the bandwidth gap that exists between LAN and WAN. Inverse multiplexing is exactly the opposite of traditional m ....etc

Overview
Multiplexing is sending multiple signals or streams of data on an information line at the same time in the form of a single, more complex signal and then separating the signals at the receiving end.
Inverse Multiplexing is combining multiple low speed streams of data to form a single higher-speed data stream. The sending and receiving ends use an inverse multiplexer with one high speed input stream.
Analog Transmission
Each signal is assig ....etc

Definition
Inverse multiplexing is a term that describes a scalable wide area access solution that is truly the opposite of traditional multiplexing. With traditional multiplexing, multiple data streams are combined and transmitted together over a single high-speed circuit. Inverse multiplexing, on the other hand, uses multiple circuits that act as a single logical channel to transmit a high-speed data stream. Because the term inverse multiplexing is a bit unwieldy, the shorter terms
