Title:
MULTI-CORE PROCESSOR SYSTEM, ALLOCATION PROGRAM, CONTROL PROGRAM, ALLOCATION METHOD AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2012/014312
Kind Code:
A1
Abstract:
A CPU (#0) detects an allocation instruction of a process (1). The CPU (#0) acquires the time remaining after removing the CP of a handler (B), which is the process time of a handler (A), from the time (handler (B) Dt) between the time of the handler (B) event occurrence, which is the interrupt process allocated to a CPU (#1), and the handler (B) execution limit. The CPU (#0) determines whether or not the acquired remaining time is greater than or equal to the process time (process (1) CP) for the process in which a process (1) interrupt disable is defined. In other words, in the case of the process (1) having been allocated to the CPU (#1), the CPU (#0) determines whether or not compliance with the handler (B) Dt is possible even if a handler (B) event occurs during the execution of the process (1). Compliance with the handler (B) Dt is determined to be possible when the handler (B) event occurs during the execution of the process (1). Hence, the CPU (#0) allocates the process (1) to the CPU (#1).
