Firewall implementation method, chip, electronic equipment and computer readable storage medium

The invention discloses a firewall implementation method, a chip, electronic equipment and a computer readable storage medium. The method comprises the steps that an initiating domain sends an access request to a secondary firewall connected with a target domain; the secondary firewall judges whether the initiating domain is allowed to perform resource access on the target domain or not; wherein both the initiating domain and the target domain comprise a main control domain and a secondary control domain, and the domain identifiers of the initiating domain and the target domain are different. According to the invention, the isolation problem of complex SoC resources in a multi-system and multi-application scene is solved by deploying two stages of firewalls at the NoC and the equipment end. 本发明公开了一种防火墙实现方法、芯片、电子设备及计算机可读存储介质，该方法包括：发起域向目标域所连接的二级防火墙发送访问请求；所述二级防火墙判断是否允许所述发起域对所述目标域进行资源访问；其中，发起域和目标域均包括主控域、次控域，且所述发起域与所述目标域的域标识不同。本发明通过在NoC及设备端部署两级防火墙解决复杂SoC资源在多系统多应用情景下的隔离问题。
