The complexity of high performance digital systems has rapidly increased. When we design such systems in a system-on-chip (SoC), lots of predesigned intellectual properties (IPs) are integrated to build a system. To verify the functionality of such systems, conventional simulation methods take extremely long time and they have limited debugging capability due to the existence of many predesigned IPs...
Wireless video interphone cannot only provide portability, but also connect people through video communication, so it gains more and more interest in consumer electronics. To design such systems, it needs high performance video processing engine. In this paper, a Multi-processor system on a chip (MPSoC) is designed, in which there are one 32-bit RISC CPU and a low power, high performance H.264 codec...
We present a high-performance and low-power pure-hardware accelerator for decoding H.264/AVC video. We propose novel VLSI architectures for every stage of the decoding pipeline. We wrap the decoder core with an AMBA bus interface, integrate it into a multimedia SOC platform, and verify it with FPGA prototyping. In order to reduce external memory traffic, we propose a memory fetch unit to increase...
An important share of the consumer electronics market is focused on devices capable of running multimedia applications, like audio and video decoders. In order to achieve the performance level demanded by these applications, it is important to develop specialized hardware IPs in order to cope with the most computational intensive parts. Nowadays, designers are facing the challenge of integrating several...
To deal with nowaday multi-standard audio and video processing, a heterogeneous multi-core SOC architecture is presented in this paper, which is composed of a general purpose RISC processor, an audio processing enhanced DSP and dedicated video processing accelerators. To exploit the task level concurrency among audio-video media decoding, an efficiency and flexible HW/SW cooperating architecture is...
