Multi-processor is not a new technology, but with the development of modern silicon technology, it is possible to integrate multiple cores in a single chip package, which is called multicore processor. Whether in the desktop personal machine, or embedded applications, multicore processor has been a general trend, due to the requirement of high performance and design problems in single-core processor. Surrounded multi-screen provides a better sense of reality, which is widely used in the surveillance, military, exhibitions, and so on. With the advantages in parallel processing, multicore technology has an important practical significance and a broad prospect in these applications. In this paper, an exploration on multicore architecture is mainly focused on, from the perspectives of processing elements, memory hierarchy, and on-chip interconnection. A basic platform for multi-screen display is implemented on the Xilinx field programmable gate array (FPGA), and it illustrates that there is a 3.6 times higher performance than the corresponding single-core design, which provides a helpful guidance and revelation to further researches.

Nowadays, China is stepping into an aging society, and most people care about their personal health with the Chinese economic development. Chronic-diseases have become the major threat to the elder people in China. In order to ensure a real-time health care for the elders, we propose health cloud platform with IoT for community health service. The platform includes IoT health services subsystem, health cloud application service subsystem and data management subsystem. The System development and service scheme is composed of six parts according to the function: front-end data acquisitioning module, message middleware, storage center, data mining center, medical graphics image processing center and presentation layer. The health cloud platform has two main functions: real time medical care technology and personalized health service. The successful deployment of health cloud can take demonstration for others application, and promote itself cloud computing technologies development.
