Recent research has shown that in mobile devices, energy efficiency of the total system does not scale at the same pace with the energy efficiency of the silicon. The reason has been attributed to overheads in software, and in the context of multi-media codecs a new approach has been proposed. In this approach hardware accelerators are scheduled quasi-statically thus decreasing the interfacing overhead...
The computing power of microprocessors has exponentially increased in the past few decades, so the support to compute intensive multimedia applications has increased too. With such improved computing power, memory subsystem deficiency becomes the major barrier to support video decoder on the Digital Signal Processor (DSP). H.264/AVC becomes the next generation of video codec for embedded systems....
Porting MP3 decoder effectively on a given hardware platform ADSP-BF533 EZ KITLITE is discussed in this paper [1]. Data structure layout, proficient data placement and data memory/cache handling for porting MP3 decoder are discussed. Hardware features and advanced instructions are availed for effective implementation of MP3 modules to reduce the MIPS. Results show MP3 decoder implementation consumes...
