Exploiting Cache in Multimedia

چکیده
The paper explores cache strategies for multimedia. Although many architectural improvements have been designed for multimedia, the cache structure and the standard caching policies of general-purpose processors exhibit poor performance in exploiting the 2D spatial locality typical of programs handling and processing images. In this paper we propose a novel caching approach suitably tailored to the requirement of multimedia programs. Our proposal exploits hardware pre-fetching for allocating in cache blocks of data that satisfy the 2D spatial locality requirements. Results refer to a benchmark suite of multimedia program including MPEG decoding and image processing programs with different data dependency and access scheme to image

Intelligent content caching for mobile devices
Newer mobile devices are equipped with multiple network interfaces that can be used to preemptively download multimedia content in an efficient and cost effective manner. We propose a content selection algorithm for such push-based multimedia content caching scenarios. Our approach improves cache hit rates by exploiting correlations between users who request similar content: we use this informa...
متن کاملA Multidimensional Software Cache for Scratchpad-Based Systems
In many kernels of multimedia applications, the working set is predictable, making it possible to schedule the data transfers before the computation. Many other kernels, however, process data that is known just before it is needed or have working sets that do not fit in the scratchpad memory. Furthermore, multimedia kernels often access two or higher dimensional data structures and conventional...
متن کاملExploiting Superword-Level Locality in Multimedia Extension Architectures
In this paper, we describe an algorithm and implementation of locality optimizations for architectures with instruction sets such as Intel’s SSE and Motorola’s AltiVec that support operations on superwords, i.e., aggregate objects consisting of several machine words. We treat the large superword register file as a compiler-controlled cache, thus avoiding unnecessary memory accesses by exploitin...
متن کاملA standard Interactive Multimedia eBook Generator Engine for e-Learning Process
Introduction: Using standard authoring tools is essential to promote E-Learning in teaching-learning process. Learning content in medical sciences often consists of multimedia elements. On the other hand, it is frequently required to revise and update the medical content. Hence, access to the authoring tools that can encompass multimedia elements and allow easy content revision is helpful in e-...
متن کاملExploring the Use of Hyper-Threading Technology for Multimedia Applications with Intel® OpenMP* Compiler
Processors with Hyper-Threading technology can improve the performance of applications by permitting a single processor to process data as if it were two processors by executing instructions from different threads in parallel rather than serially. However, the potential performance improvement can be only obtained if an application is multithreaded by parallelization techniques. This paper pres...
