  • In this paper, we propose a novel hardware architecture to facilitate the applicable SoC chip design of H.264/SVC which has a great deal of advancement in the international standardization in recent. Moreover, a new C-model simulator based on the proposed hardware system will be presented to support optimal SoC circuit development. Since the proposed SVC decoder is consist of some hardware engine for processing of major decoding tools and core processor for software processing, the system is simply implemented with the conventional embedded system. To improve the feasibility and applicability, and reduce the decoder complexity, the hardware decoder architecture is constructed with only the consideration of IPPP structure scalability without using the full B-picture. Finally, we present results of decoder hardware implementation and decoded picture to show the effectiveness of the proposed hardware architecture and C-model simulator.

  • This paper presents the implementation of the bluetooth headset and the audio gateway connected to the mobile Phone in the embedded environment. The bluetooth module includes the BC02 processor chip, the BCSP02 firmware and the bluelab software Including bluetooth protocol stack. The above components in the bluetooth module developed at CSR company are used as the development environment. The application program using API functions supported by bluelab is coded by C language and loaded on the flash ROM of the bluetooth module. The cail processing capacity measuring the call setup time and the clearing time between the audio gateway and the headset is considered as the performance parameter of the developed systems. As a call setup and clearing time between the audio gateway and the headset is about 88.8ms, the call processing capacity is about 11 calls per second. Therefore the performance result is satisfied in the aspect of the call processing time.
