Patent number: 11520493Abstract: Processing circuitry may support a secure domain and a less secure domain, where secure information associated with a secure software process is prevented from being accessed by a less secure software process in the less secure domain. Shared resource is accessible to both secure and less secure software processes. In response to detection of an anomaly condition, allocation policy for the shared resource is switched from a shared allocation policy to a secure-biased allocation policy. The secure-biased allocation policy has a stronger bias of resource allocation to secure software processes than the shared allocation policy.Type: GrantFiled: July 23, 2019Date of Patent: December 6, 2022Assignee: ARM TECHNOLOGY (CHINA) CO.
