Organic electroluminescence device

The method for executing, by a microprocessor, an instruction code including a first bit field used for controlling the microprocessor and a second bit field used for specifying opecode and/or operand, the method comprising the steps of:

• setting an operation mode of the microprocessor in a first mode or a second mode, the microprocessor executes an instruction code in a first instruction set in the first mode and executes an instruction in a second instruction set in the second mode;
• fetching an instruction code in either of the first instruction set or the second instruction set from an instruction memory;
• extracting in information from the first bit field of the instruction code fetched in the fetching step;
• controlling the microprocessor based on the information extracted in the extracting step and the operation mode of the microprocessor;
• decoding the second bit field of the instruction code fetched in the fetching step;
• and
• executing the instruction code based on the decoding result,
• wherein the information contained in the first bit field in the first instruction set is different from the information contained in the first bit field in the second instruction set, and
• wherein a bit position of the first bit field is the same in the first instruction set and the second instruction set.

The method for executing in instruction code included in one of a first instruction set and a second instruction set by a microprocessor, wherein each instruction code of the first instruction set and the second instruction set includes a first bit field and a second bit field, the method comprising the steps of:

• fetching and instruction code included in the second instruction set from an instruction memory;
• extracting an information regarding to power management of the microprocessor from the first bit field of the instruction code fetched in the fetching step;
• power managing the microprocessor based on the information extracted in the extracting step;
• decoding the second bit field of the instruction code fetched in the fetching step;
• and
• executing the instruction code based on the decoding result,
• wherein the first bit field does not contain the information regarding to power management in the first instruction set and the first bit field contains information regarding to power management in the second instruction set,
• wherein the second bit field contains opecode and/or operand in both the first instruction set and the second instruction set, and
• wherein a bit position of the first bit field is the same in the first instruction set and the second instruction set.
