片上网络能够用来为多核/众核片上系统提供高速的核间通信.如何保证片上网络通信的实时性是目前片上网络研究亟待解决的问题之一.本文针对有环的通信集提出了两种实时调度算法CS-VC和CS-TI,并给出了通信集用这两种算法可调度的通信集利用率界限(也称为通信集可调度的充分条件).实验部分将CS-VC和CS-TI与目前最先进的能用于有环通信集的实时调度算法进行了比较,实验结果表明CS-VC和CS-TI有更高的接收率,并且当通信集和片上网络规模越小时,CS-VC和CS-TI的接收率越高.CS-TI与CS-VC相比虽然接收率较低,但CS-TI无需额外的片上网络结构作为支持更便于实现.
On-chip network can be used to provide high-speed core-to-core communication for multi-core / in-the-core systems and how to ensure real-time on-chip network communication is one of the most urgent problems to be solved in on- Real-time scheduling algorithm CS-VC and CS-TI, and gives the communication set utilization of these two algorithms can be scheduled by the communication set utilization limits (also known as communication set schedulable sufficient conditions.) Experimental part of the CS-VC and CS- CS-TI is compared with the most advanced real-time scheduling algorithm that can be used for ring communication set. The experimental results show that CS-VC and CS-TI have higher receiving rate, and when the size of communication set and on-chip network is smaller , CS-VC and CS-TI higher reception.CS-TI and CS-VC compared to the low reception, but CS-TI without additional on-chip network structure as a more convenient support.
