摘要
For the application scenario of short-range, high speed wireless communication between consumer AR glasses terminal and smart phones, a customized wireless MAC protocol with ultra-high speed, low power, low latency characteristics is presented. First, based on the requirements of the application scenario, quantitative analysis of specifications such as effective throughput and latency are presented, then the detailed protocol is designed through the specifications above. Compared to the existing ECMA-398 protocol, the effective throughput standard S increased from 71% to 86%. By introducing priority mechanism for various type of data transmission, the maximum transmission latency is reduced by one order of magnitude, which is less than 1mS. This paper completed the construction and simulation of system-level models, RTL-level coding and verification according to the analysis above. Finally, the protocol was tested and verified through the FPGA platform. Simulation and test results show that the customized MAC protocol designed in this paper can fulfill the requirement of the scenario much better.
