Abstract
A central processing unit (CPU) is disclosed. The CPU includes two or more processing cores and a power control unit to regulate voltage applied to the CPU based upon the number of processing cores that are active.
Claims29
A central processing unit (CPU) comprising:
- two or more processing cores;
- and
- a power control unit to regulate voltage applied to the CPU by adaptively adjusting a direct current (DC) loadline based upon the number of processing cores that are active.
A method comprising:
- determining at a central processing unit (CPU) a number of processing cores that are activated;
- and
- adjusting a direct current (DC) loadline based upon the number of processing cores that are active.
A computer system comprising:
- a power converter;
- a central processing unit (CPU), coupled to the power converter, including:
- two or more processing cores;
- and
- a power control unit to regulate voltage applied to the CPU by adaptively adjusting a direct current (DC) loadline based upon the number of processing cores that are active;
- and
- a main memory device coupled to the CPU.
