Computing device and method of processing secure services for computing device |
摘要 |
A method of processing secure services is provided. The method is applied to a processing unit of a computing device to control the processing unit to process multiple secure services. The computing device includes a storage unit. The method includes: controlling a core of the processing unit to perform following steps in a secure mode: accessing the storage unit to obtain a first command that includes first secure service information, processing a first secure service associated with the first secure service information according to the first command, and accessing the storage unit to obtain a second command that includes second secure service information. During a period from a time point that the core accesses the storage unit to obtain the first to a time point that the core accesses the second command, the core is controlled to stay in the secure mode. |

1. A method of processing secure services, applied to a processing unit of a computing device to control the processing unit to process multiple secure services, the computing device comprises a storage unit, the method comprising:
controlling a core of the processing unit to perform following steps in a secure mode:
accessing the storage unit to obtain a first command that comprises first secure service information;processing a first secure service associated with the first secure service information according to the first command; andaccessing the storage unit to obtain a second command that comprises second secure service information, comprising:
storing the second command into the storage unit;issuing a notification to the core which is in the secure mode;controlling the core to access the storage unit according to the notification to obtain the second command; andprocessing a second secure service associated with the second secure service information according to the second command;wherein, during a period from a time point that the core accesses the storage unit to obtain the first command to a time point that the core accesses the storage unit to obtain the second command, controlling the core to stay in the secure mode. |
