In this paper, we propose an improved hardware-software codesign methodology for implementation on embedded system. The codesign flow begins with profiling of the system algorithm. With the analysis of profiling, constraint of computation requirement for the application system, and the provided software-hardware resources on the specific embedded system platform, we partition the application system...
The appearance of the new MPEG-4 standard offers opportunities for real-time implementations of MPEG-4 encoders suitable for a wide range of applications, including video conferencing, digital storage media, television broadcasting, Internet streaming, and communication. With the rapid development of FPGA, SOPC has been paid great attentions in the area of image and video processing in recent years...
Processors that deploy reconfigurable fabrics to implement application-specific accelerators on-demand obtained significant attention within the last decade. They trade-off the flexibility of general-purpose processors with the performance of application-specific circuits without tailoring the processor towards a specific application domain like application specific instruction set processors (ASIPs)...
In this paper, we propose a self-reconfigurable platform which can reconfigure the architecture of DCT computations during run-time using dynamic partial reconfiguration. The scalable architecture of DCT computations can compute different number of DCT coefficients in the zigzag scan order to adapt to different requirements, such as power consumption, hardware resource, and performance. We propose...
For effective digital rights management (DRM) of multimedia in the framework of embedded systems, both watermarking and cryptography are necessary. In this paper, we present a watermarking algorithm and VLSI architecture that can insert a broadcaster's logo in video streams in real-time to facilitate copyrighted video broadcasting and internet protocol television (IP-TV). The VLSI architecture, when...
To reduce the bandwidth requirement and the size of frame memory for video decoding, embedding a compressor/decompressor on the chip is a well-known solution. Video compression has been developed for a long time and numbers of algorithm have been proposed. Those algorithms show us that enhancing the complexity can reach better performance. However, algorithm with higher complexity is more difficult...
To optimize system performance for a specific target application, embedded system designers may add some new instructions, called application-specific instructions (ASIs), by automatic design flow. In past days, most application-specific instruction-set processor (ASIP) researches focus on reducing instruction latency to improve performance regardless of the impact of memory access. In this paper,...
