Microcontroller unit controlling plurality of registers in accordance with precision of data to be operated, and compiler thereof |
摘要 |
A precision storage unit stores the required precision of data. A register is formed of a 8-bit register. A decoder decodes the data precision stored by the precision storage unit. Control is provided of the power supply and clock supply to the registers in accordance with the decoded result of the decoder. Accordingly, power consumption of the microcontroller unit can be reduced.
