The object is achieved by a portable electronic device including: a first casing; a second casing disposed opposed to one of surfaces of the first casing and capable of changing a position relative to the first casing while maintaining a state where opposed surfaces are opposed; and a heat source disposed in the second casing. Surface of the second casing includes: a first region which is covered with the first casing in a first state where the first and the second casings are opposed and is exposed to the outside in a second state where the position relative to the first casing is changed and area of the opposed surfaces of the first and the second casings decreases from the first state; and a second region which is always exposed to the outside in both of the first and the second states.

Abstract: An access request arbitration section, a data amount management section and a resource control section are provided between a plurality of masters and a shared resource. The data amount management section manages access data amounts passing between the plurality of masters and the resource. The access request arbitration section executes arbitrary arbitration of issuing access permission to a master determined according to the access data amount at any timing, in addition to periodic arbitration of issuing access permission to any of the masters at fixed-interval arbitration timing. If an access request of less than a defined data amount is granted in periodic arbitration, the remaining access chance can be used in arbitrary arbitration.
