Abstract
Problem: A master cannot use a built-in memory as an independent memory in the case where a memory does not use peripherals.
Solution: A memory control apparatus includes main memories (for example, RAM) 35-1, 35-2, peripherals 40-1, 40-2 having built-in memories (for example, RAM) 43-1, 43-2, a master 20 for accessing the main memoirs and the built-in memories, and a access mode setting register for setting the access mode of the access object. Furthermore, the memory control apparatus includes an address decoder 31 for decoding an address from the master 20 and outputting the decoding results, and selectors 42-1, 42-2 for selecting access information including the decoding results being given to the built-in memories corresponding to the set access mode.
