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

Two Techniques for Fast Computation of Constrained Shortest Paths

abstract:
Computing constrained shortest paths is fundamental to some important network functions such as QoS routing, MPLS path selection, ATM circuit routing, and traffic engineering. The problem is to find the cheapest path that satisfies certain constraints. In particular, finding the cheapest delay-constrained path is critical for real-time data flows such as voice/video calls. Because it is NP-complete, much research has been designing heuristic algorithms tha ....etc

Numerical simulation of rotor stator interaction is crucial for turbo machinery improvement since it allows the optimization of blade path design In addition the numerical simulation of rotor stator interaction makes it possible to predict the location and variation of hot spots on blades which is extremely useful in the turbine thermal design However simulation of rotor stator interaction is notorious for being computationally expensive To reduce the turnaround time and cost MFLOP a parallel code based on the message passing interface l ....etc

Two Techniques For Fast Computation of Constrained Shortest Paths
A major obstacle against implementing distributed multimedia applications such as web broadcasting, video teleconferencing and remote diagnosis, is the difficulty of ensuring quality of service (QoS) over the Internet. A fundamental problem that is present in many important network functions such as QoS routing, MPLS path selection and traffic engineering is to find the constrained shortest path that satisfies a set of constraints. For interactive real time traffic, t ....etc
