Motion Estimation by Quadtree Pruning and Merging
In this paper we propose a rate-distortion optimized motion estimation algorithm that is built upon a quadtree structure. Each node of the quadtree represents a block in the curre...

Efficient Motion Estimation using Sorting-Based Partial Distortion Search
An efficient motion-estimation algorithm based on partial block distortion using sorted significant features including bit-plane and mean is proposed. The proposed algorithm can o...

A Call Level Adaptive Bandwidth Allocation Scheme Based on Lyapunov Control Theory
— In this paper, we propose an adaptive capacity allocation scheme at the call level for a blocked call cleared loss system. The scheme aims to maintain the connection blocking p...

Resource Sharing in EDF-Scheduled Systems: A Closer Look
Resource sharing in priority-based systems can give rise to priority-inversion and blocking, wherein a job’s execution is delayed because a lower-priority job holds some resourc...

Optimizing memory transactions
Atomic blocks allow programmers to delimit sections of code as ‘atomic’, leaving the language’s implementation to enforce atomicity. Existing work has shown how to implement...
