| Popis: | 92 With the advent of wireless network, the demand of mobile multimedia information has become an urgent issue. To deal with such a situation, a novel compression approach of H. 264 Specification has been proposed to provide a more efficient way of delivering video information even under a bandwidth-limited wireless network environment. However, the complexity of this specification was seen more than that of other standards; hence, motivating the application of dedicated hardware to conquer this computing bottleneck while satisfying the high compression performance requirements. In this thesis, considering to handling the increasing complexity revealed by the specification, the chip design is also gradually focused on the hardware/software co-design chip rather than the hardware-only logic circuit. In other words, the concept of the system-on-a-chip (SoC) was also embedded into the whole design. Then, by taking the burden reduction of verification and debug tasks into consideration, a novel idea in anticipation of reaching the construction of a verification environment with higher bandwidth and shorter response time is also completed. Namely, the peripheral component interconnection (PCI) bus was effectively included in the verification of SoC, where PCI bridge circuits along with a general-purpose processor were also designed in full cooperation such that the validation of the completed H. 264 IP can be well accomplished. Besides, in order to validate the effectiveness of the study, a hardware and software co-design methodology is employed for the implementation of H. 264 compression kernel. Furthermore, the H.264 chip is fully realized with the aid of field programmable gate array (FPGA) and tested through the video clip data. From the test results, they help support the proposed method for the applications considered. |
