摘要： An information processor has at least one interface unit by which the processor is coupled to a peripheral equipment. The interface unit can selectively generate either a first mode signal or a second mode signal when the processor performs an interruption operation according to request from the peripheral equipment. When the processor performs the interruption operation in response to the first mode signal, a stack operation for saving information necessary to restart a program execution which is stopped by the interruption to a stack memory is performed before start of the interruption operation. While the processor can perform the interruption operation in response to the second mode signal without the stack operation, whereby an improved processor with less overhead can be provided.

摘要： A serial data processor is coupled to a single data line and a single clock line for serial data transfer in synchronism with a clock signal. The data processor comprises a shift register coupled to the serial data line and operated to serially output the data in synchronism with a clock on the clock line, and an output buffer connected to receive the data serially outputted from the shift register and coupled to sequentially output the received data to the data line. This output buffer includes a push-pull driver having an output connected to the data line and an input driven by the data serially outputted from the shift register. A clock counter is coupled to receive the clock on the clock line so as to maintain the push-pull driver in an operable condition until the count value reaches a predetermined value and to bring the output of the push-pull driver into a floating condition after the count value reached a predetermined value. There is provided a data line control circuit coupled to the data line and controlled by the clock counter to bring the data line to a high level after the count value of the clock counter reaches the predetermined value.

摘要： A data transfer controller for controlling DMA data transfer between a memory area and a peripheral unit. The data transfer controller has a first register which stores address information relative to a predetermined address of the memory area. A DMA control unit uses the first register and a second register to perform the DMA data transfer between the memory area and the peripheral unit. The data transfer controller also has a third register for storing data used for accessing the memory area of the DMA transfer. An updater is used to update the contents of the third register whenever a memory access uses the third register and is different from a memory access associated with data transfer between the memory area and the peripheral unit. Finally, a counter changes the contents of the third register in one direction whenever the data transfer between the memory area and the peripheral unit is performed. The counter changes the contents of the third register in an opposite direction whenever memory access using the third register is performed.

摘要： A data processor comprises an interrupt processing request controller receiving processing requests from peripheral devices for generating an interrupt request. An execution unit has a first mode of executing the interrupt processing in accordance with a user's program and a second mode of executing the interrupt processing in accordance with a microprogram while maintaining an internal condition concerning execution of a program. The controller operates to selectively inhibit the execution of the interrupt processing in the first mode, but to basically allow the execution of the interrupt processing in the second mode.

摘要： A date data processor verifies whether an inputted date data exists or not. Inputted date data is stored in an input register which is composed of three sections according to month, day and year. A first calculating unit calculates the days difference between the inputted date data and a reference date, and the results are temporarily stored. A second calculating unit then performs an inverse calculating to arrive at a date based on the previously calculated days difference. The resulting date is compared with the inputted date to complete the verification.

摘要： A circuit for removing noise from an incoming input signal and for producing a noise free output signal in synchronism with a predetermined synchronization scheme. The memory signal is shifted through a plurality of series connected memory stages in sequence with first and second clock pulse sequences. The output signals of predetermined memory stages are compared and a noise free output signal is produced in response to stage output signals being simultaneously present at the output terminal of predetermined memory stages. The circuit does not utilize capacitors and resistors and is suitable for fabrication as an integrated circuit.
