Apparatus and method of loading program code through interface

A method for driving a computer system, wherein the computer system comprises a first logic unit for executing a first program code, and a second logic unit for executing a second program code, the method comprising:

• providing a storage unit for storing the first program code and the second program code;
• providing a first interface for transmitting received data to the first logic unit;
• and
• providing a second interface for transmitting received data to the first interface;
• wherein the second logic unit reads the second program code from the storage unit and executes the second program code, and transmits the first program code from the storage unit to the second interface, and the first program code is further transmitted to the first logic unit via the first and the second interfaces.

A method for loading program codes, wherein the method is utilized in a system comprising a first logic unit, a second logic unit, and a storage unit which stores a first program code and a second program code, the method comprising:

• the first logic unit reading the first program code stored in the storage unit;
• the first logic unit executing the first program code;
• the first logic unit reading the second program code stored in the storage unit;
• the first logic unit transmitting the second program code to the second logic unit via an interface;
• and
• the second logic unit receiving the second program code.
