Device having shared memory and method for displaying data

摘要

A digital processor including a shared memory and a data outputting method are provided to supply a power supply voltage to only an internal component of a processor, which operates corresponding to a function performed by the processor, thereby reducing power consumption. A digital processor includes a power supply(260), a shared memory(230), n processors(210,220) and a switch(265). The power supply provides a power supply voltage. The n processors are respectively connected to the shared memory through independent buses. The switch controls supply of the power supply voltage to at least one processor or at least one internal component of the processor. The switch controls supply of the power supply voltage to at least one internal component of a first processor, a second processor or at least one internal component of the second processor in response to a power supply voltage control instruction inputted from the first processor.
