In this Paper, an improved L-Expressnet Protocol is proposed by supplementing slot-extension function. This protocol is Proposed to complement the shortcomings of the conventional protocol which is used for the medium access control (MAC) in LAN. We analyzed the protocol in channel utilization viewpoint and compared the result with that of the conventional L-Expressnet medium access control (MAC) protocol. From this result. we showed that the channel utilization of the improved L-Expressnet protocol added slot-extension function is superior to that of the conventional Protocol.

In this Paper, an improved protocol is proposed by supplementing a control station for transmission cycle management and slot-extension function. This protocol is proposed to complement the shortcomings of the conventional L-Expressnet protocol which is used for round robin process in bus topology. We analyzed the improved protocol in channel utilization viewpoint and compared the result with that of the conventional Protocol. From this result, we showed that the channel utilization of the improved protocol is superior to that of the conventional protocol when a maximum normalized propagation delay is increased.

Coarse-grained reconfigurable architecture (CGRA)-based multi-core architecture aims at achieving high performance by kernel level parallelism (KLP). However, the existing CGRA-based multi-core architectures suffer from much energy and performance bottleneck when trying to exploit the KLP because of poor resource utilization caused by insufficient flexibility. In this work, we propose a new ring-based sharing fabric (RSF) to boost their flexibility level for the efficient resource utilization focusing on the kernel-stream type of the KLP. In addition, based on the RSF, we introduce a novel inter-CGRA reconfiguration technique for the efficient pipelining of kernel-stream on CGRA-based multi-core architectures. Experimental results show that the proposed approaches improve performance by up to 50.62 times and reduce energy by up to 50.16% when compared with the conventional CGRA-based multi-core architectures.

In this Paper. Multi-channels L-Expressnet protocol is proposed by supplementing multi-channels control method. This protocol is proposed to complement the shortcomings of the basic protocol which is used for the medium access in LAN. We analyzed the protocol in channel utilization viewpoint and compared the result with that of the Expressnet and L-Expressnet protocol. From this result, we showed that the channel utilization or the Multi-channels L-Expressnet Protocol is superior to that of the other medium access control methods when the channel traffic is increased.
