  • Data processing system and method for switching between heterogeneous accelerators
    Patent number: 9223581
    Abstract: A method for operating a system on chip includes receiving an acceleration request signal generated upon execution of an application program, in response to receipt of the acceleration request signal, comparing a current usage of a central processing unit (CPU) with a threshold value to generate a comparison signal, and performing switching between heterogeneous accelerators to accelerate a function executed by the application program in response to the comparison signal.

  • Hot-plugging of multi-core processor
    Patent number: 8880924
    Abstract: A method of hot-plugging a multi-core processor includes monitoring respective workload levels of multiple processor cores, hot-plugging off a first core among the processor cores upon determining that its workload level has fallen below a lower reference value, and hot-plugging on a second core among the processor cores upon determining that its workload level has risen above an upper reference value while the first core is hot-plugged off.
