PROBLEM TO BE SOLVED: To efficiently access a memory from a plurality of processes.SOLUTION: When a controller 6 is in context with a series of consecutive accesses to a memory 2, the controller 6 limits masters 1-i which are allowed to have a bus use right among a plurality of masters 1-1 to 1-4 such that the total context number of the masters 1-i which are allowed to have a bus use right of a bus 3 is equal to or less than a prescribed number based on the configuration of a memory 2. |
