Problems solved by technology

When the firmware of such a high-performance machine is applied to a low-cost machine using the same multi-core CPU, although the low-cost machine does not need to give priority to performance, since it is assigned the control tasks that make the most use of the available cores, Therefore, "clock gating" to stop the clock of the core cannot be performed sufficiently, and power is wasted.

Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0044] figure 1 It is a block diagram showing the configuration of the image processing device 1 according to one embodiment of the present invention. In this embodiment, an all-in-one machine having multiple functions such as a copy function, a print function, a facsimile function, and a scan function is used as an image processing device.

[0045] The image processing apparatus 1 includes, in addition to the CPU 11, a ROM 12, a RAM 13, a scanner unit 14, a storage unit 15, a printer unit 16, a facsimile (FAX) unit 17, an operation panel 18, a network interface (network I / F) 19, and a USB interface ( USB (I / F) 20 and the like are connected to the CPU 11 via the bus 2 .

[0046] The aforementioned CPU 11 functions as a controller to overall control the image processing apparatus 1 as a whole, and controls basic functions such as a copy function, a print function, a sc...

Abstract

The invention provides an image processing apparatus and the like for using universal firmware in a multi-core CPU image processing apparatus, even a performance priorty mode and electricity saving priorty mode and different modes is set. An image processing apparatus includes: a multi-core CPU having multiple cores; a selector that selects either a first mode or a second mode with respect to allocation of control tasks to the cores of the multi-core CPU; and an allocator that allocates control tasks to the cores of the multi-core CPU by the symmetric multiprocessing technology when the first mode is selected by the selector, and that allocates control tasks to the cores of the multi-core CPU by the asymmetric multiprocessing technology when the second mode is selected by the selector.

Description

technical field [0001] The present invention relates to an image processing device such as an all-in-one machine having multiple functions such as a copy function, a printer function, a facsimile function, and a scan function, and a method for allocating control tasks executed in the device. Background technique [0002] In recent years, there has been a tendency that the performance of hardware such as CPUs has improved, and that the price of hardware has been reduced more and more significantly. In image processing devices, the hardware resources of high-performance machines are also applied to small, low-speed, low-cost machines, thereby The development cost of hardware is suppressed. [0003] When the same hardware is used for both high-performance and low-cost machines, if the same hardware can also be used for firmware for controlling the image processing device and realizing the functions, development costs will be further reduced. [0004] However, high-performance ...
