Abstract
An image processing apparatus having a plurality of functional units that respectively execute predetermined functions, a method of controlling the apparatus, the apparatus manages a memory with a plurality of areas, and allocates the plurality of areas of the memory to the plurality of functional units respectively. Then, when, in a power saving state, at least one of the plurality of functional units is caused to transition into a power saving state, the apparatus stops a refreshing of the area of the memory allocated to the functional unit that is caused to transition into the power saving state.
Claims8
An image processing apparatus having a plurality of functional units that respectively execute predetermined functions, the apparatus comprising:
- a management unit configured to manage a memory with a plurality of areas;
- an allocation unit configured to allocate the plurality of areas of the memory to the plurality of functional units respectively;
- and
- a control unit configured to control so as to, when, in a power saving state, at least one of the plurality of functional units is caused to transition into the power saving state, stop a refreshing of the area of the memory allocated to the functional unit that is caused to transition into the power saving state.
A method of controlling an image processing apparatus having a plurality of functional units that respectively execute predetermined functions, the method comprising:
- managing a memory with a plurality of areas;
- allocating the plurality of areas of the memory to the plurality of functional units respectively;
- and
- controlling so as to, when, in a power saving state, at least one of the plurality of functional units is caused to transition into the power saving state, stop a refreshing of the area of the memory allocated to the functional unit that is caused to transition into the power saving state.
A non-transitory computer readable storage medium storing a program for causing a computer to execute a method of controlling an image processing apparatus having a plurality of functional units that respectively execute predetermined functions, the method comprising:
- managing a memory with a plurality of areas;
- allocating the plurality of areas of the memory to the plurality of functional units respectively;
- and
- controlling so as to, when, in a power saving state, at least one of the plurality of functional units is caused to transition into the power saving state, stop a refreshing of the area of the memory allocated to the functional unit that is caused to transition into the power saving state.
