Abstract
A microcomputer has: a CPU; memory; a direct memory access controller which controls access to the above memory without passing through the CPU; a plurality of peripheral resources, each having prescribed functions corresponding to a given real resource number, and issuing an access request to the direct memory access controller to perform data transfer with the memory; and, a resource conversion unit, which performs signal conversion between the direct memory access controller and the plurality of peripheral resources. A portion of the peripheral resources among the plurality of peripheral resources are associated with logical resource numbers of the direct memory access controller by the resource conversion unit.
