Abstract
Official abstract text for this publication.
For flexibly setting up an execution environment according to contents of processing to be executed while taking stability or a security level into consideration, the multiple processor system includes the execution environment main control unit 10 which determines CPU assignment at the time of deciding CPU assignment, the execution environment sub control unit 20 which controls starting, stopping and switching of an execution environment according to an instruction from the execution environment main control unit 10 to synchronize with the execution environment main control unit 10 , and the execution environment management unit 30 which receives input of management information or reference refusal information of shared resources for each CPU 4 or each execution environment 100 to separate the execution environment main control unit 10 from the execution environment sub control units 20 a through 20 n , or the execution environment sub control units 20 a through 20 n from each other.
First claim
Opening claim text (preview).
What is claimed is: 1. A multiple processor system comprising: a plurality of processors including a primary processor and a plurality of secondary processors; a primary execution environment running at all times to perform primary processing and including: a group of the processors always including the primary processor, where each secondary processor is able to exit and rejoin the group; a primary operating system executable on the group of the processors; a plurality of…
