Title:
PROGRAM EXECUTION CONTROL METHOD AND VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/159616
Kind Code:
A1
Abstract:
According to the present invention, a function group in which data conflict does not occur can be executed in parallel with a plurality of cores, and function pairs in which data conflict occurs are time-separated and executed. When the number of cores which can execute functions in parallel is N (N is an integer of 2 or greater), a process barrier 20 is provided with (N-1) checker functions 22 and one limiter function 23. The checker function 22 determines whether a lead entry of a lock-free function queue LFQ1 is the checker function 22 or the limiter function 22, repeats reading the lead entry of the lock-free function queue LFQ1 in either case, and terminates the process in neither case. The limiter function 23 is an empty function that ends without performing any process.
