摘要: PURPOSE: A system on chip and power gating method of a core therefor are provided to reduce leakage power by predicting wake-up latency. CONSTITUTION: A memory unit(112) stores a database. The database includes core access information and the wakeup latency items of a core(114). The core access information includes an access time for a system on chip(102) in order to access the core by analyzing the branch of a code block. A control unit(106) searches for the power of the core by determining the request of core usage based on instruction point information and the core access information.
