中文摘要：
虚拟通道控制器的设计是实现虚拟通道技术的关键．基于FPGA实现技术，利用VHDL硬件描述语言设计实现了一种适用于网格、半环网、环网三种拓扑结构的虚拟通道控制器．该虚拟通道控制器工作频率能够达到689MHz，FPGA资源占用率仅为1％，是一种高效的虚拟通道控制器设计方案．
英文摘要：
Virtual channel technology is one of important technologies to improve the performance of network communications, and the design of virtual channel controller is the key to implement virtual channel technology. This paper designs and implements a virtual channel controller based on FPGA using VHDL. It is suitable for mesh, semi-torus and torus topology network-on-chips. Its operating frequency can reach 689MHz and it only occupies 1% of the FPGA resources. It is a low-cost and high-performance design of the virtual channel controller.
