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.

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.

The present invention relates to a fuse option circuit of an integrated circuit and a method thereof. More particularly it concerns a fuse option circuit comprising: a first fuse formed on a chip, which is cut by providing a larger electric current than a set value; a second fuse formed on the chip identically with the first fuse; a fuse cutting means providing a cutting current loop to the first fuse in response to a fuse cutting signal; and an option signal generating means which produces a fuse option signal by comparing resistance values of the first and second fuses. Accordingly, even if the first use is abnormally cut, the fuse option can be precisely provided by comparing the first fuse having a changed resistance after cutting process with the second fuse keeping an initial resistance value. Therefore, the reliability of a fuse option of an integrated circuit can be improved.
