CPU activity sharing method for computing unit, involves dedicating high and low priority lines to interruptions for undertaking operations according to kernel operating system and open operating system, respectively

摘要

The method implementing a high priority fast interruption request line (6) and a low priority interruption request line (7). The high priority line is dedicated to the interruptions for undertaking operations according to a real time constraint kernel operating system (10). The low priority line is dedicated to the interruptions for undertaking operations according to an open operating system (20). The kernel system does not contain a background task and is executed like an interruption of the open operating system. An independent claim is also included for a computing unit comprising a CPU.
