摘要： In a multiple power source semiconductor integrated circuit that is manufactured using a process which generates a large leakage current, supply of power to a function block that is not being used is stopped to reduce unnecessary power consumption. A multiple power source semiconductor integrated circuit (1) includes first to fourth function blocks (11) to (14) that are supplied with power from first to fourth power supply circuits (3) to (6), respectively, and a power supply control circuit (40) that controls supply of power by the first to fourth power supply circuits (3) to (6) under the control of a microcomputer as the first function block (11). The power supply control circuit (40) halts the supply of power to the first to fourth function blocks (11) to (14) when receiving prescribed data from the first function block (11), and restarts the supply of power when receiving a first or second interrupt signal (55) or (56) from outside.

摘要： A braking/driving control apparatus for a vehicle includes a basic control unit which calculates and outputs a target axle torque based on a target acceleration and a driving resistance of the vehicle and which determines an axle torque for a power train of the vehicle and an axle torque for a braking apparatus of the vehicle based on the calculated target axle torque, a sliding-down prediction determining unit which determines whether there is a possibility that the vehicle slides down rearwards on an uphill road, and a sliding-down preventing process executing unit which performs a process for reducing a possibility that the vehicle slides down, based on a determination result of the sliding-down prediction determining unit. After the sliding-down prediction determining unit determines that there is the possibility, the sliding-down preventing process executing unit controls the basic control unit to calculate and output the target axle torque so as to reach an axle torque which is obtained by reducing a predetermined positive amount form an estimated value of an axle torque necessary for the vehicle to achieve the target acceleration against the driving resistance.

摘要： There are provided a buffer circuit buffers data between a synchronous circuit and an asynchronous circuit, and a control method therefor. There are also provided an interface circuit that controls data transfer between a synchronous memory circuit and the asynchronous circuit, and a control method therefor, which are used in the buffer circuit and the control method therefor. A data buffer circuit that is interposed between an image processing system and a main system includes a one-port RAM, a control signal generating section, an subsequent cycle address generating section, and a first selector. The first selector selectively outputs the present cycle address to an address of the one-port RAM when an access to the one-port RAM is a write access, and selectively outputs the subsequent cycle address to the address of the one-port RAM when the access to the one-port RAM is a read access.

摘要： A microcontroller, connected to a memory which stores instructions and data, includes an instruction execution unit for reading instructions and data from the memory and processing the read instructions and a prefetch circuit unit that receives the instructions and data read from the memory and detects pseudo instructions included in the instructions and data. A pseudo instruction precedes a branch instruction and indicates the existence of the branch instruction and the branch to address. The prefetch circuit unit includes a prefetch buffer connected between the instruction execution unit and the memory for temporarily storing instructions and data being transferred from the memory to the instruction execution unit and a pseudo instruction buffer for temporarily storing instructions and data located at the address of the branch instruction which follows the pseudo instruction. Then, if the branch is taken, the branch to instructions have been prefetched and are immediately available to the instruction execution unit by way of the pseudo instruction buffer.

摘要： A processor for performing calculations based on an instruction code, the number of bits of which is not an integer multiple of a byte. The instruction code is divided into higher order bits and lower order bits. The number of the lower order bits is an integer multiple of one byte. A memory stores the lower order bits in a lower order bit storage section and the higher order bits in a higher order bit storage section. The lower order bits and the corresponding higher order bits are read from the memory in the same cycle when generating the instruction code.
