HPS-HSR-PRP

交換機IP內核

HSR-PRP 交換機(HPS)是一款IP內核,用於實現可靠性以太網通信的高可用性無縫冗余和並行冗余協議(HSR和PRP版本3,IEC 62439-3-條款5和4各自的)標準。HSR-PRP交換機是一個完整的硬件解決方案,可以在低成本FPGA上實現。

用於Xilinx Vivado工具的HSR/PRP交換機IP內核

通過利用新的Xilinx Vivado工具,HPS 可以輕松集成到你的FPGA設計中,該工具允許在圖形用戶界面中使用該IP內核,並以簡便的方式配置IP參數。

connector

Keeping up with the times and innovating - Explore more potentials of TSN with Hongke

Time Sensitive Networking (TSN) is a new generation of network technology based on the evolution of the standard Ethernet architecture. It takes traditional Ethernet as the network foundation and provides a data link layer protocol specification for deterministic data transmission capability through mechanisms such as clock synchronization, data scheduling, and network configuration. Compared with traditional Ethernet, TSN can provide microsecond-level deterministic services, reduce the complexity of the entire communication network, and realize the convergence of information technology (IT) and operation technology (OT). With its precise clock synchronization, deterministic traffic scheduling, and intelligent and open operation and maintenance management framework, TSN can ensure the high-quality transmission of multiple business traffic in a common network, and it has both performance and cost advantages, and it is the development trend of the future network. This is the future trend of network development.

Currently, TSN technology has a high level of discussion in the automotive, industrial, rail transportation, and aerospace fields. As a non-vendor-bound real-time communication protocol, we believe that TSN technology has a good application prospect.

Welcome to contact us to explore and learn the integration of TSN technology with various industries, and actively promote more applications on the ground to jointly build a new world of intelligent interconnection.
