Abstract

A software control device, comprising: a judging unit (306), the judging unit (306) judging whether software in startup and software in execution are accessing the same shared resource; and a control unit (307), in the judging unit (306) When it is determined that the same shared resource is being accessed, the control unit (307) controls the running software so as to temporarily stop the running software.

Description

Technical field [0001] The invention relates to a software control device, a software control method, and a software control program for controlling software. Background technique [0002] The technology of high-speed starting software has been developed all the time. Failure to accept user operations during software startup is the cause of user disappointment. As a technology for high-speed startup of software, the following technology has been disclosed: for example, it has a table storing the allocation rules of CPU (Central Processing Unit), so that a specific CPU or CPU group is processed preferentially (for example, refer to the following patent documents 1). [0003] In addition, as a technique for transmitting commands to each CPU, a technique for broadcasting a cache coherency request to each CPU is disclosed (for example, refer to Patent Document 2 below). In addition, when new software with a high priority is started, in addition to the technology of Patent Document 1...
