Provided is a delay adjustment device for adjusting delay of a strobe signal, which specifies when to read a data signal on a data line, with respect to the data signal in order to perform data transfer with an external memory. A testing unit 150 included in a delay adjustment unit is provided with a memory bandwidth monitoring unit 212 that monitors memory bandwidth in use on the data line used for data transfer with a memory circuit. The testing unit 150 performs delay adjustment when the memory bandwidth in use is lower than a predetermined threshold. Delay adjustment is performed by delaying the strobe signal from the data signal by a variety of predetermined delays and determining whether data transfer is successful at each delay, calculating an optimal delay, and thereafter delaying the strobe signal by the calculated delay.

An IC current measuring apparatus is provided between an IC and a substrate. The IC current measuring apparatus electrically connects each of a plurality of IC-facing terminals and a different one of a plurality of substrate-facing terminals. Especially, resistances are each inserted into a path between an IC terminal targeted for measurement and a substrate terminal corresponding thereto. Furthermore, the IC current measuring apparatus is provided with terminals each used to measure a voltage between both ends of an inserted resistance corresponding thereto. Accordingly, a measurer who measures current flowing through an IC-facing terminal can measure the current flowing through the IC-facing terminal by providing the IC current measuring apparatus between the IC targeted for measurement and the substrate and measuring a voltage between both ends of an inserted resistance corresponding to the IC terminal through which current he/she wishes to measure flows.

摘要:
A leg training equipment has a base fixed in place, a support portion configured to support a part of a user's body, and a coupling mechanism provided between the base and the support portion. The coupling mechanism movably couples the support portion to the base such that a load applied to a leg of the user by the user's own weight changes by a relative positional displacement between a foot position and a position of center of gravity of the user. In addition, the coupling mechanism limits a movable direction of the support portion such that at least when the load applied to the leg increases, a direction of the relative positional displacement between the foot position and the position of center of gravity is substantially limited to a direction of flexion and extension of knee joint. Thereby, it is possible to efficiently provide the user with an exercise that applies less load on the knee joint.
摘要:
A semiconductor integrated circuit ensures to reserve a required memory bandwidth at low cost. A memory bandwidth monitoring unit 1210 calculates a required memory bandwidth, monitors the usage condition of the memory, and outputs the following information to a reconfiguration control unit 1120. The information is necessary to reconfigure a reconfiguration unit 1110 into a logic unit and a temporary buffer both of which are scalable depending on the usage condition. According to information, the reconfiguration control unit 1120 controls the reconfiguration unit 1110. The buffer is for storing data accessed to or from the memory by each bus master. The logic unit acts as a bus master that only uses a portion of the memory bandwidth that remains unused during the time no access request to the data storage unit 1002 issued by a bus master unit having a higher priority level is being executed.

摘要:
Bus transfer efficiency is improved in bus communication that uses a shared memory, based on a communication origin master 101 selectively using an arbitration completion notification signal and a memory access completion notification signal. Based on the arbitration completion notification signal, the communication origin master 101 issues a command issue permission signal to the communication destination master 102, and the communication destination master 102 generates and issues a command for accessing the shared memory 12. Based on the memory access completion notification signal, the communication origin master 101 issues a command issue permission signal to the communication destination master 102, and the communication destination master 102 generates and issues a command for accessing the shared memory 12.
