This paper presents the IP net telephony system using computer network, and proposes the design proposal based on FPGA telephone terminal. The hardware circuit of IP telephone terminal is designed using FPGA device EP1C3T144C8. In order to control the telephone terminal, the system uses a FPGA chip inserting the 51IP core with TCP/IP protocol. The system uses speed compression algorithm on ADPCM to...
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...
That's very difficult for traditional display screen to achieve this function that is synchronous display of the industrial production data, because the traditional display screen can just displays static data and images. In this paper, we propose the multimedia dynamic display screen which can achieve the dynamic display of production data from various kinds of companies by this following way. At...
On the detailed function and requirement, we design a kind of single chip VDR (voyage data recorder) structure based on Nios II; Making full use of the idea of SOPC, simplifying the hardware design mostly and reducing the cost and power consumption significantly. It has significant meanings in both technologies and applications.
