Growing wire delays will force substantive changes in the designs of large caches. Traditional cache architectures assume that each level in the cache hierarchy has a single, uniform access time. Increases in on-chip communication delays will make the hit time of large on-chip caches a function of a line's physical location within the cache. Consequently, cache access times will become a continuum of latencies rather than a single discrete latency. This nonuniformity can be exploited to provide faster access to cache lines in the portions of the cache that reside closer to the processor. In this paper, we evaluate a series of cache designs that provides fast hits to multi-megabyte cache memories. We first propose physical designs for these Non-Uniform Cache architectures (NUCAs). We extend these physical designs with logical policies that allow important data to migrate toward the processor within the same level of the cache. We show that, for multi-megabyte level-two caches, an adaptive, dynamic NUCA design achieves 1.5 times the IPC of a Uniform Cache architecture of any size, outperforms the best static NUCA scheme by 11%, outperforms the best three-level hierarchy-while using less silicon area-by 13%, and comes within 13% of an ideal, minimal hit latency solution.

The present work describes a reliable improved gradient optical flow estimation system using FPGAs. This structure is based on space-temporal processing and the use of steerable filters. This model can be enhanced using psychophysical and bioinspired properties according to biological vision in order to mimic the singularity and the performance of mammalians. Experimental results and the resources used to analyze the associate customizability of the system are discussed.
Fast, accurate, and effective performance analysis is essential for the design of modern processor architectures and improving application performance. Recent trends toward highly concurrent processors make this goal ...

Short and efficient memory tests is the goal of every test designer. To reduce the cost of production tests, often a simple test which covers most of the faults, e.g. all simple (unlinked) faults, is desirable to eliminate most defective parts;a more costly test can be used thereafter to eliminate the remainder of the bad parts. Such a test-cost efficient approach is used by most manufacturers. In addition, system power-on tests are not allowed a long test time while a high fault coverage is desirable. The authors propose a new realistic fault model (the disturb fault model), and a set of tests for unlinked faults. These tests have the property of covering all simple (unlinked) faults at a very reasonable test time compared with existing tests.

Based on the homotopy analysis method, a general analytic technique for strongly nonlinear problems, a Maple package of automated derivation (ADHO) for periodic nonlinear oscillation systems is presented. This Maple package is valid for periodic oscillation systems in rather general, and can automatically deliver the accurate approximations of the frequency co and the mean of motion δof a nonlinear periodic oscillator. Based on the homotopy analysis method which is valid even for highly nonlinear problems, this Maple package can give accurate approximate expressions even for nonlinear oscillation systems with strong nonlinearity. Besides, the package is user-friendly: One just needs to input a governing equation and initial conditions, and then gets satisfied analytic approximations in few seconds. Several different types of examples are given in this paper to illustrate the validity of this Maple package. Such kind of package provides us a helpful and easy-to-use tool in science and engineering to analyze periodic of this Maple package from the is published publicly. nonlinear oscillations.

Pervasive computing is a field where many different entities come into play. In particular, development of useful applications in the field of pervasive healthcare requires dealing with substantial levels of complexity regarding the management of the pervasive environment where users and applications coexist. Service oriented middleware architectures simplify the task of creating those applications and turn the management of pervasive environments into a productive activity. We present our ongoing approach to the design of such a middleware architecture, known as the Smart Environment Application architecture.
