On the Communication Mechanism in RISE

通信机制的研究及功能实现是实时交互仿真环境ＲＩＳＥ设计的关键技术。本文在分析仿真系统网络环境和蛀孔寻径原理的基础上，建立系统的通信模型，进行相应的算法设计，给出具体的函数实现，并与有关通信机制进行原理对比。分析表明：本设计具有通信开销小、通信速度快的特点。同时，也提高了用户编程透明性。

We proposed a Real time Interactive Simulation Environment (RISE) . Communication mechanism was the key to the design of RISE but only outlined in Ref.. We now discuss in detail the communication mechanism in RISE. The design philosophy of the communication mechanism in RISE is quite distinctive in that hardware shares at least equal responsibility with software, whereas only software plays this role in existing products. Fig.2 shows schematically the system communication mechanism model which includes communication functions and intelligent routing units. The intelligent routing units undertake a considerable part of communication such as packing, routing, etc., thus relieving the software of a big percentage of its workload. We also take advantage of wormhole routing technique to reduce the delays in communication. Our design philosophy leads to the high efficiency of the implemented communication module of RISE: low overhead, high communication speed.
