Embodiment Construction

[0036] In this embodiment, the priority-based dynamic wireless medium access control method in the wireless network on chip is to calculate and obtain the priority of the data packet according to the length of the data packet in the wireless port on the wireless node and the waiting time of the data packet by the calculation module; According to the priority of the data packet, the central control unit uses the gating mechanism to dynamically authorize the right to use the wireless medium and allocate the sending time.

[0037]In this embodiment, the dynamic wireless medium access control method is to operate according to the following steps:

[0038] Step a, use wireless link to carry out data transmission for the long-distance communication between subnetworks, be that the basic routing node BR in the subnetwork i transmits the data packet to the transmission buffer TB of wireless router WR; The area TB adopts the first-in-first-out buffer queue FIFO (Frist In Frist Out, FIF...

Abstract

The invention discloses a priority-based dynamic wireless medium access control method in a wireless on-chip network. The method comprises the following steps: according to the length of data packetsto be sent in a wireless port on a wireless node and the waiting time of the data packets to be sent, a calculation module calculates the priority of the data packets to be sent; The central control unit dynamically grants the wireless medium usage right and allocates the transmission time by using the gating mechanism according to the priority of the data packets. The invention can make full useof radio resources, and can give consideration to the priority of data packets, so that short data packets are sent first, the system response speed is improved, bandwidth resources are reasonably allocated, and the best utilization rate of available bandwidth is ensured. So that multiple WIs can share the wireless channel without any interference and the best utilization of available bandwidth isensured.

Description

technical field [0001] The invention belongs to an integrated circuit chip communication control method, which is used for optimizing wireless communication in a wireless on-chip network, and more specifically relates to a priority-based dynamic wireless medium access control method in a wireless on-chip network. Background technique [0002] With the development of integrated circuit technology and the promotion of market demand, the number of IP cores (Intellectual Property cores) that can be integrated on a single chip continues to increase, and the scale of the Network on Chip (NoC) becomes larger and larger. In traditional wired NoC communication architectures, wired multi-hop transmission suffers from high latency and low energy efficiency. To this end, researchers at home and abroad have proposed a new solution, that is, Wireless Network-on-Chip (WiNoC). This solution is based on the traditional wired NoC architecture. By introducing high-bandwidth, low-latency, and ...
