METHODS AND SYSTEMS FOR DETECTING UNDERVOLTING OF PROCESSING CORES |
| 摘要 |
An example method for detecting undervolting of a core of a multi-core processing unit includes reading a value of an entry counter and a value of an exit counter. The value of the entry counter indicates that a core of the multi-core processing unit has begun executing a code section, and the value of the exit counter indicates that the core has completed executing the code section. The method also includes determining that the core was undervolted when: (i) the value of the entry counter is not the same as the value of the exit counter, and (ii) a core power resource does not satisfy a power resource threshold for the core. |

1. A method of detecting undervolting of one or more cores of a multi-core processing unit, comprising:
reading a value of an entry counter and a value of an exit counter, the value of the entry counter indicating that a core of the multi-core processing unit has begun executing a code section, and the value of the exit counter indicating that the core has completed executing the code section; and determining that the core was undervolted when: (i) the value of the entry counter is not the same as the value of the exit counter, and (ii) a core power resource does not satisfy a power resource threshold for the core. |
