Abstract
A semiconductor device capable of suppressing performance degradation and systems using the same are provided. The semiconductor device includes a plurality of processors CPUand CPU, a scheduling device(ID) connected to the processors CPUand CPUfor controlling the processors CPUand CPUto execute a plurality of tasks in real time, memoriesandaccessed by the processors CPUand CPUto store data by executing the tasks, and access monitor circuitsfor monitoring accesses to the memories by the processors CPUand CPU. When an access to the memory is detected by the access monitor circuit, the data stored in the memoryis transferred based on the destination information of the data stored in the memory
