| 摘要 | A multicore processor system includes core configured to detect a process assignment instruction; acquire a remaining time obtained by subtracting a processing time of interrupt processing assigned to an arbitrary core of a multicore processor from a period that is from a calling time of the interrupt processing to an execution time limit of the interrupt processing, upon detecting the process assignment instruction; judge if the remaining time acquired at the acquiring is greater than or equal to a processing time of processing defined to limit an interrupt in the process; and assign the process to the arbitrary core, upon judging that the remaining time is greater than or equal to the processing time of the processing defined to limit an interrupt in the process. | ||

| 主权项 | 1. A multicore processor system comprising core configured to: detect a process assignment instruction; acquire a remaining time obtained by subtracting a processing time of interrupt processing assigned to an arbitrary core of a multicore processor from a period that is from a calling time of the interrupt processing to an execution time limit of the interrupt processing, upon detecting the process assignment instruction; judge if the remaining time acquired at the acquiring is greater than or equal to a processing time of processing defined to limit an interrupt in the process; and assign the process to the arbitrary core, upon judging that the remaining time is greater than or equal to the processing time of the processing defined to limit an interrupt in the process. | ||
