    摘要: A master unit sends a start signal to a slave unit. When receiving the start signal from the master unit, the slave unit sends, to the master unit, a synchronization field that is a data train (pulse signal) indicative of a transfer clock with which the slave unit is able to perform transferring and receiving operations. The master unit sends, to the slave unit, command data in accordance with the transfer clock indicated by the synchronization field sent from the slave unit. In response to the command data sent from the master unit, the slave unit sends, to the master unit, response data in accordance with the transfer clock indicated by the synchronization field. Thus, in a communication system employing a serial data transferring apparatus of the present invention, the master unit establishes the synchronization for the data transfer, while the slave unit is free from a burden of establishing the synchronization for the data transfer. A serial data transferring apparatus is realized which can simplify the structure of the slave unit, cut the total cost, and reduce noise.

    摘要: This method is an error correction method such that, when an error is detected in a CPU with pipeline struct, a content of a register file is restored by a delayed register file which holds an execute completion state of an [Instruction N] correctly executed before this error, and a rollback control that re-executes an instruction from the [Instruction N+1] which is the next instruction of the [Instruction N] is performed. The method collects a parity check result of arbitrary Flip-Flops existing inside the CPU, and detects an error. As a result, the content of the register file is restored into the instruction execute completion state preceding to the instruction range likely to malfunction by the error, and the instruction can be roll backed from the beginning of the instruction range likely having malfunctioned by the error.

    摘要: An air temperature sensor sensing an air temperature, supplied with a pulse signal as a driving signal from a pulse signal source, senses an air temperature based on the pulse signal. While the air temperature sensor is self-heated during an electrical current supplying time period by the pulse signal, it is cooled during an electrical current halting time period. Accordingly, the self-heating of the air temperature sensor by the driving signal is suppressed, and a thermal effect on air flow rate sensing elements disposed in an air flow downstream side of the air temperature sensor is also reduced.
