摘要： A transfer-target unit outputs commands for data reading and data writing. An address generator generates control signals in accordance with the commands, and outputs the number of bytes of data first transferred by read access. A command generator generates control commands in accordance with the control signals to control an SDRAM. At this time the command generator judges the number of transferred bytes to control so that the SDRAM executes instructions in order from an instruction which is the most efficient in data transfer. That is, in the case where data is read across a bank boundary, the command generator judges which is to be executed first between read processing in a bank 0 and active processing in a bank1, to control the SDRAM. A data processor mediates data transfer between the transfer-target unit and the SDRAM in accordance with the control commands. In this way, it is possible to issue commands so as to terminate data transfer in the minimum number of cycles in the case where data read processing is continuously performed to different banks. The number of cycles required for two continuous access (access to the bank 0 and the bank 1) can be thus reduced, thereby increasing effective transfer rates of the SDRAM.

摘要： A control voltage Vin that has been input is sequentially reduced at NMOS's 111˜113 constituting means for voltage reduction. The individual voltages resulting from the voltage reduction are applied to control electrodes of MOS varactors 211˜213 constituting voltage-controlled variable-capacitance elements which are connected in parallel and, thus, the capacitance values of the individual MOS varactors 211˜213 are determined. An LC resonance circuit constituted of the MOS varactors 211˜213 and a coil 22 resonates at a specific frequency, NMOS's 23 and 24 constituting means for switching engage in on/off operation and oscillation occurs at an oscillation frequency corresponding to the voltage Vin resulting in an oscillation signal output through output terminals 3 and 4. Thus, an LC resonance circuit that allows the rate at which the capacitance values of the voltage-controlled variable-capacitance elements change to be set freely in correspondence to the particulars of design and a high-performance voltage-controlled oscillation circuit (VCO) that employs this LC resonance circuit and enables good control are provided.

摘要： A bus bridge apparatus that connects two system buses independent of each other to which a bus arbiter operating independently and located outside of the apparatus, has a function for serving as a master and a slave of the system buses, a base address holding means, and a bus address generating means. When, to access a slave device on a first system bus, a master device on a second system bus attempts to access the apparatus, generating offset from addresses received from the master device and combining the offset with base addresses previously stored in said base address holding means, to generate an access destination address in the slave device by using said bus address generating means, this bus bridge apparatus performs functions: (i) issuing the generated access destination address by serving as a bus master on the first system bus, to access the slave device; and (ii) performing data transfer between the master device and the slave device by serving as a slave of the master device on the second system bus. It is thus possible to realize mutual access between system buses having an independent arbitration function, without changing system design.
