Abstract: A bus system comprises a master, a first slave, a second slave, and a bus. The master is configured to be able to issue a second request to the second slave after issuing a first request to the first slave and before receiving a response to the first request. The bus comprises: a determination unit configured to, upon receiving the second request, determine whether to permit a transfer of the second request to the second slave; and a suspending unit configured to suspend the transfer of the second request to the second slave while it is determined by the determination unit that the transfer is not permitted. The determination unit determines whether or not the transfer is permitted based on a notification from the first slave regarding processing of the first request.

Abstract: A lever-type connector has a lever that rotates about a shaft on a first housing between a retracted position and a connection start position. The first housing and a second housing are connected by rotation of the lever from the connection start position. A detector is movable between a standby position and a detection position with respect to the lever. The lever includes a lock on an end separated from the shaft. The second housing includes a full locking portion to engage the lock when the housings are connected. The detector locks the lock at the standby position and becomes movable to the detection position when the full locking portion engages the lock. The first housing includes a housing-side lock, and the lever includes a lever-side lock that locks the housing-side lock at the retracted position. The lever-side lock is at a position different from the lock of the lever.

Abstract: A connector assembly includes a female housing (11) and a male housing (12) connectable to each other. Male terminal fittings (39) have tabs (41) projecting into a receptacle (36) of the male housing (12), and a moving plate (15) to be movably accommodated into the receptacle (36). The moving plate (15) includes a plate body (94) with positioning holes (96) enabling the insertion of the tabs (41) and a peripheral wall (95) connected to a periphery of the plate body (94) and slidable on an inner surface of the receptacle (36). An operating portion (103) for removal is provided on the peripheral wall (95) and is exposed from the receptacle (36).

Abstract: A control apparatus controls access from a plurality of masters to a memory. The apparatus comprises: an acquisition unit configured to acquire a plurality of access requests from the plurality of masters; a selection unit configured to select a scheme to be used from a plurality of different schemes for determining an access sequence in accordance with a state of a master concerning satisfaction of a performance requirement; and an execution unit configured to execute a plurality of acquired access requests in a sequence according to a selected scheme.

Abstract: Provided is a controller which issues a first write command for writing all data of a burst access operation on a memory and a second write command for writing data of a burst access operation on a memory per byte. The controller includes a holding unit configured to hold a plurality of commands requesting access to the memory and a selection unit configured to select, in a case where the holding unit holds the second write command and a command that causes a first time penalty longer than a second time penalty needed between the first write command that is issued first and the second write command that is issued next, the second write command prior to the command.

Abstract: A connector assembly includes a female housing (11) having a lever lock (28) projecting therefrom, a male housing (12) having a tubular receptacle (36). The female housing (11) is configured to fit into the receptacle (36). The receptacle (36) has a recess (71) in the form of a cutout into which the lever lock (28) enters.
