Problems solved by technology
That is, during the execution of tasks, switching between processors cannot be performed
[0015] As a result, for example, in the case of Internet browser and music reproduction, even if the Internet browser ends without network processing, the processing load on the general-purpose CPU is reduced, and if the function of music reproduction is transferred to the general-purpose CPU, the processing cannot be maintained. continuity
Therefore, it is necessary to temporarily stop music playback, etc., and cannot respond to changes in system conditions and usage conditions.

A program generating device (20) for generating a machine language program corresponding to each of a plurality of processors having mutually different command groups and sharing memory from the same source program (200), having: switching point determination A part (301) that determines a switching point in the source program (200); a program generation part that generates a switchable program for each processor based on the source program (200), so that at the switching point, the data structure of the memory consistent among a plurality of processors; and a switching judgment processing inserting unit (303) for inserting a switching program into a switchable program for causing the switchable program being executed by the first processor to be at the switching point and causing the second processor to continue executing the switchable program corresponding to the second processor from the switching point.
Description
technical field [0001] The present invention relates to a program generation device, a program generation method, a processor device, and a program processing system. In particular, the present invention relates to a program generation device, a program generation method, a processor device, and a multiprocessor system in a heterogeneous multiprocessor system having a plurality of processors having command groups different from each other and sharing memory. Background technique [0002] In digital packaged devices such as mobile phones and digital TVs, in order to achieve performance improvement and low power consumption, etc., processors that specialize the processing required for each function are often incorporated. For example, processors that specialize in prescribed processing include general-purpose CPUs (Central Processing Units) for processing web browsers, and processors that strengthen signal processing for processing audio and images. DSP (Digital Signal Proces...
