PROBLEM TO BE SOLVED: To provide a technique for accessing shared data without a waiting time due to exclusive control in a multi-core microcontroller mounted with a shared memory.SOLUTION: A data buffer is multiplexed, each arithmetic device 101, 102 performs update processing or reference processing on a different multiplexed data buffer, and one data buffer updated by data update processing is synchronized with a multiplexed data buffer in a period shorter than an execution cycle of the data update processing by an arithmetic device 101, 102 different from an arithmetic device 101, 102 executing the data update processing. |
