Abstract:
A microcontroller includes multiple ways each including only one tag. When a first access and a second access are accesses performed in succession to consecutive addresses, and when the second access is the access through a first way, a cache controller performs the following operations: prefetching to the way whose tag value is smaller by 1 than the tag value corresponding to the first way when the second access is the access in the direction in which the address is incremented with respect to the first access; and prefetching to the way whose tag value is greater by 1 than the tag value corresponding to the first way when the access is in the direction in which the address is decremented.

Claim (Index 6):
The semiconductor device according to  claim 5 ,\n wherein when the address change direction flag corresponding to the second way and the address change direction flag corresponding to the first way match each other, and when the tag value corresponding to the second way is continuous in the direction opposite to the direction that the address change direction flag indicates with respect to the tag value corresponding to the first way, the cache controller is configured to allow prefetching of data to the second way after the prefetching of data to the area within the first way, and wherein when the address change direction flag corresponding to the second way does not match the address change direction flag corresponding to the first way, or when the tag value corresponding to the second way is not continuous in the direction opposite to the direction that the address change direction flag indicates with respect to the tag value corresponding to the first way, the cache controller is configured, after the prefetching of data to the area within the first way, to allow prefetching of data to the area within the first way in the direction opposite to the direction indicated by the address change direction flag corresponding to the first way after the second access within the first way.
