Design and Simulation of Ring Network-on-Chip for Different Configured Nodes

The network-on-chip(NoC)technology is frequently referred to as a front-end solution to a back-end problem.The physical substructure that transfers data on the chip and ensures the quality of service begins to collapse when the size of semiconductor transistor dimensions shrinks and growing numbers of intellectual property(IP)blocks working together are integrated into a chip.The system on chip(SoC)architecture of today is so complex that not utilizing the crossbar and traditional hierarchical bus architecture.NoC connectivity reduces the amount of hardware required for routing and functions,allowing SoCs with NoC interconnect fabrics to operate at higher frequencies.Ring(Octagons)is a direct NoC that is specifically used to solve the scalability problem by expanding each node in the shape of an octagon.This paper discusses the ring NoC design concept and its simulation in Xilinx ISE 14.7,as well as the communication of functional nodes.For the field-programmable gate array(FPGA)synthesis,the performance of NoC is evaluated in terms of hardware and timing parameters.The design allows 64 to 256 node communication in a single chip with‘N’bit data transfer in the ring NoC.The performance of the NoC is evaluated with variable nodes from 2 to 256 in Digilent manufactured Virtex-5 FPGA hardware.

Kinematic synthesis method for the one-degree-of-freedom jumping leg mechanism of a locust-inspired robot

The one-degree-of-freedom(DOF) mechanism has a simple structure, convenient control, and high stiffness, and it has been applied in many micro jumping robots. Meanwhile, the six-and eight-bar mechanisms can satisfy more complex motion requirements than the four-bar jumping leg mechanism and they have good application prospects. However, the lack of effective design methods limits the application range of these mechanisms. In this work, a type and dimensional integration synthesis method was proposed with the one-DOF six-bar leg mechanism as the research object. The initial tibia and femur were determined based on the kinematic chain atlas, and configuration design was implemented through the superposition of links.When a closed chain was formed in the superposition process, the feasible range of the link length was analyzed by considering the constraint conditions. The proposed method innovatively establishes the relationship between the kinematic chain atlas and the configuration, and the feasible length ranges of the links can be quickly obtained simultaneously. Several examples were provided to prove the feasibility of the kinematic synthesis method. This method provides a useful reference for the design of one-DOF mechanisms.
