Benefits of technology

The present invention relates to an information processing apparatus that uses plural processors that can individually perform information processes. More specifically, the invention is about an information processing apparatus that includes a first processor and a second processor that has higher power consumption and capability than the first processor. The invention also includes a temperature monitoring module and a processor switching control module that can prevent thermal runaway of the second processor by stopping its operation and causing the first processor to perform an information process. The technical effect of the invention is to improve the performance and efficiency of information processing by dynamically switching between the processors based on their capabilities and power consumption, and to prevent thermal runaway of the processors.

Problems solved by technology

However, in the conventional switchable method, the temperatures of the processors are not considered at the time of switching among the processors.
Accordingly, by using the conventional switchable method, it is difficult to prevent thermal runaway of the processors.

first embodiment

[0024]FIG. 1 illustrates an information processing apparatus according to a The embodiment may be applied to an information processing apparatus using plural processors that can individually perform information processes. As the information processing apparatus according to the embodiment, there will be described a notebook-type personal computer (hereinafter, referred to as a personal computer) that includes two GPUs capable of individually performing a display control process and supports the switchable GPU method in which one GPU is used for a display control process by dynamically switching between the two GPUs as needed.

[0025]As shown in FIG. 1, the personal computer 10 includes a computer main body 11 and a display unit 12 as a display device.

[0026]The computer main body 11 has a thin box-type casing. In the center portion of the top face of the casing, a keyboard 13 as an operation input device is disposed. On the front side of the top face of the casing of the computer main...

second embodiment

[0154]FIG. 11 illustrates an exemplary internal configuration of a personal computer 10A according to the Only the configuration of the personal computer 10A represented in FIG. 11, in which the function as the GMCH 22 is included in the CPU 21 and the ICH 28 is replaced by the PCH 50 (Platform Controller Hub), is different from that of the personal computer 10 represented in FIG. 1. Other configurations and operations are not substantially different from those of the personal computer 10 represented in FIG. 1. Thus, a same reference symbol is assigned to each configuration that is the same as that of the personal computer 10, and a description thereof is omitted here.

[0155]The CPU 21 controls the processing operation of the personal computer 10 in accordance with a program that is stored in a recording medium such as the HDD 29 that can be read by the CPU 21. The CPU 21 loads a processor switching program stored in the HDD 29 and data required for executing the program into the ma...
