In this paper, a novel decomposition approach and VLSI implementation of the chroma interpolator with great hardware reuse and no multipliers for H.264 encoders are proposed. First, the characteristic of the chroma interpolation is analyzed to obtain an optimized decomposition scheme, with which the chroma interpolation can be realized with arithmetic elements (AEs) which are comprised of only adders. Four types of AEs are developed and a pipelining hardware design is proposed to conduct the chroma interpolation with great hardware reuse. The proposed design was prototyped within a Xilinx Virtex6 XC6VLX240T FPGA with a clock frequency as high as 245 MHz. The proposed design was also synthesized with SMIC 130 nm CMOS technology with a clock frequency of 200 MHz, which could support a real-time HDTV application with less hardware cost and lower power consumption.

In this paper, we discuss the applications of UC/OS-II and DSP(digital signal processor) in area of harmonic analyzing. In this research, the FFT algorithm is employed, and the realization of FFT on DSP is discussed. The whole system is based on UC/OS-II operation system, which coordinate all the tasks about the system. The system based on DSP+ARM and UC/OS-II improve the reliability and real time quality. The hardware design and software design are proposed in this paper, with flow chart and part of routine codes shown.

Hardware design specifications for a real time picture processor are presented. Attention is concentrated on those unique aspects of the hardware that make possible high speed storage and processing of images. The latter are the major contributors to rapidity by which various image transforms may be accomplished—speeds which are great enough to warrant the term real time.

In order to discard some disadvantages of traditional astronomical navigation positioning, such as manual computation and time-consuming, we design a special calculator for locating ship's position, which not only make astronomical navigation positioning calculation quickly and operate instrument simply, but also convenient to carry. The system based on the theory of sun shift line positioning principle use the 32-bit microcontrollers based on ARM Cortex-M3 kernel as the core controller. In this paper, we give hardware design and software process of the system. Through actual test, the results of the testing value and actual value can tally well. Its calculation process only needs a few seconds, also could greatly improve the real-time and accuracy of positioning.
