Abstract: Centralized computing platforms integrate diverse heterogeneous resources and provide high computing power under limited conditions, which now becomes a research hotspot of the new generation of electronic information system. Existing commercial ethernet switching chips are designed for large-scale and high-performance networks such as data center, which cannot meet the requirements of centralized computing platform. In order to provide high-efficiency and low-power agile connection capability for mobile high-end equipment, the College of Computer Science and Technology, National University of Defense Technology proposes an end-to-end agile switching solution, and independently developes YHHX(Yin He Heng Xin)-DS40 agile switching chip, which is a powerful supplement to the existing domestic Ethernet switching chips. YHHX-DS40 integrates four 10 Gigabit Ethernet interfaces and four Gigabit Ethernet interfaces with full line-speed switching capability. Besides, application layer fine-grained switching and unified connection of heterogeneous resources are supported only with 1.6W typical power consumption.

Key words: agile switch, low-power consumption, embedded, protocol-independent, heterogeneous
