A method and apparatus to initialize a central processing unit (CPU). The apparatus includes: the CPU decoding a program command of an electronic device and executing the command; a first memory to store a booting program to boot the electronic device and initialization data to initialize the CPU; and a CPU initialization unit to read the booting program and the initialization data from the first memory and to send the booting program and the initialization data to the CPU, wherein the CPU is initialized by using the initialization data. Accordingly, the apparatus can initialize the CPU without using a memory such as an EEPROM, and hence reduce the manufacturing costs of an electronic device. Further, since a memory such as an EEPROM for initialization of the CPU is not used, and therefore does not need to be programmed, the memory region for the program is not necessary, and therefore the size of a board can be reduced.
