A calculation accuracy of a communication quality for use in selecting a communication path is improved. A radio communication device includes: a first calculator configured to calculate a transmission quality indicator value of each of a plurality of parent candidate nodes on the basis of a transmission frame transmitted from an own device to each of the plurality of parent candidate nodes; a second calculator configured to calculate a reception quality indicator value of each of the parent candidate nodes on the basis of a reception frame transmitted from each of the plurality of parent candidate nodes and received by the own device; and a selector configured to select a parent node for use in the communication path among the plurality of parent candidate nodes on the basis of the transmission quality indicator value and the reception quality indicator value.

Radio communication device, radio path control methods and programmes

An apparatus for mask data processing in which a design data format of computer aided design for an integrated circuit is transformed into mask data of an actual integrated circuit. The apparatus includes a data transformation unit for transforming a design data format of computer aided design for an integrated circuit into mask data of an actual integrated circuit, and a picture image display unit for monitoring the transformation of the design data format into the mask data. The data transformation unit includes a control central processor unit for controlling the mask data transformation, and a picture processing processor having a calculation central processor unit for a unit field.
