Abstract: A communication device is configured to wirelessly connect to an electronic apparatus. The communication device comprises a first communication unit and a second communication unit of a same type as that of the first communication unit and a control unit configured to control the first communication unit and the second communication unit. The control unit is configured to acquire a communication situation of the first communication unit with electronic apparatus and another communication situation of the second communication unit with electronic apparatus. The control unit is configured to execute an allocation process for determining a connection destination of an electronic apparatus to the first communication unit or the second communication unit based on the communication situations.

Abstract: A communication device includes a first communication unit and a second communication unit and is configured to wirelessly connect to an electronic apparatus. The first communication unit and the second communication unit operate in the same communication protocol. The first communication unit is configured to wait for a connection request from the electronic apparatus, and the second communication unit is configured to wirelessly connect to the electronic apparatus from which the first communication unit received a connection request. The first communication unit is configured to wait, where the first communication unit is not connected to the electronic apparatus, for a connection request in a first mode in which a waiting time period is relatively long, and the first communication unit is configured to wait, where the first communication unit is connected to the electronic apparatus, for a connection request in a second mode in which the waiting time period is relatively short.

Abstract: A communication device comprises a first communication unit that performs switching between transmission operation and reception operation in response to a value of a given bit of a clock, and a second communication unit of a same type as that of the first communication unit. In the communication device, a value of the given bit of the clock of the first communication unit and a value of the given bit of the clock of the second communication unit are synchronized with each other.

Abstract: A communication device comprises a first communication unit and a second communication unit of a same type as that of the first communication unit. The first communication unit or the second communication unit is configured to transmit, after wireless connection to an electronic apparatus is established, a waiting instruction signal for instructing the electronic apparatus to enter a state in which the electronic apparatus waits for a connection request.

Abstract: A communication device is configured to wirelessly connect to an external apparatus. The communication device comprises a first communication unit and a control unit configured to control the first communication unit. The first communication unit is configured to operate as one of a master and a slave. When the first communication unit is connected to a given external apparatus, the control unit is configured to control a period during which the first communication unit operates as the slave in response to a communication situation of the first communication unit with a different external apparatus from the given external apparatus.

Abstract: A first communication control unit and a second communication control unit share a single transmission and reception unit. The second communication control unit maintains connection with a terminal device while the first communication control unit is scanning frequency channels to search for an access point. When a search processing unit 104 detects an access point, the second communication control unit 200 switches the frequency channel for use in communication with the terminal device to the channel used in the detected access point.

Abstract: A multi-port instruction/data integrated cache which is provided between a parallel processor and a main memory and stores therein a part of instructions and data stored in the main memory has a plurality of banks, and a plurality of ports including an instruction port unit consisting of at least one instruction port used to access an instruction from the parallel processor and a data port unit consisting of at least one data port used to access data from the parallel processor. Further, a data width which can be specified to the bank from the instruction port is set larger than a data width which can be specified to the bank from the data port.
