Abstract: Bandwidth information including a plurality of slots each having highest priority order information for arbitrating access conflict, and priority master information for specifying, as a priority master, one or more of a plurality of masters whose latency in accessing a memory serving as a shared resource is desired to be reduced are included as arbitration information. When an arbitration section arbitrates access conflict while switching the slots in the bandwidth information at each of predetermined arbitration timings, if there is an access request from the priority master specified in the priority master information, the arbitration section changes the sequence of the slots in the bandwidth information so as to allow the priority master to access the memory with priority.

Abstract: A resource management apparatus comprises an information selection unit having an operation speed different to an operation speed of a common resource and selecting from information transferred from a plurality of bus masters, a buffer unit for storing the information selected by the information selection unit, and a timing adjustment unit for controlling timings of the information selections in the information selection unit. The information selection unit selects the information comprised of a command and data transferred from any of the plurality of bus masters to the common resource. The timing adjustment unit controls the timings of the information selections in the information selection unit so that the sum of time required for selecting a plurality of predetermined volumes of information in the information selection unit and the sum of processing time in the common resource are substantially equal to each other.

Abstract: A low-voltage driven semiconductor device is simple to fabricate, operates at high speed, and consumes low power. The semiconductor device is made of first and second MISFETs connected in series. The MISFETs have channels of the same conduction type. If the conduction type is n, the drain and gate of the first MISFET are connected to the high-potential side of a power source. The source and well of the second MISFET are connected to the low-potential side of the power source. The well of the first MISFET and the gate of the second MISFET are connected to a signal input terminal. A voltage applied to ends of the MISFETs and the potential fluctuation range of a signal supplied to the signal input terminal are each set to be lower than a voltage determined by a built-in potential (a forward withstand voltage) of a pn junction between a well of the first MISFET and a diffusion layer of the same. The diffusion layer is one that is adjacent to the second MISFET.
