Application launch time in mobile systems is critical in many cases because it can adversely affect user experience. Android has employed several software techniques to reduce application launch time. For example, Android shares memory space among applications to reduce the loading time of libraries. It also keeps applications in memory, even after the applications are terminated, to reduce start-up...
Video has become a key multimedia application in embedded systems and various standards have been developed for specific purposes. As a result, high performance and flexible functionality are required to design embedded systems for video CODEC. SIMD extension is well known as a representative approach to overcome performance bottlenecks of programmable processors, especially in the multimedia operations...
Three-dimensional (3-D) integration technology dramatically increases the memory bandwidth by stacking memory directly on the top of a processor. This paper proposes a stream buffer based adaptive prefetching scheme to exploit the massive memory bandwidth provided by 3-D integration technology. Performance simulation results show that the proposed stream buffer based adaptive prefetching scheme with...
