    摘要: In a system including LSIs, the signature register used for self-testing the LSI functions is assigned to one register accessible by a machine instruction. The signature is calculated in the self-test operation, and the calculation result is updated depending on the result from the execution of the machine instruction. With the above technical idea, the test function for the LSI function is available not only for the test mode, but also for the normal operation. This simplifies the self-test program for testing the functions of the application system.

    摘要: A microprocessor device has an operand address register for storing an operand access address for an operand access, an access generation instruction address register for storing an access generation instruction address having caused the operand access and an operand data register for storing input/output data for the address indicated by the operand address. A multiplexer, whose operation is controlled by a selection signal provided from outside of the microprocessor, outputs the operand address or the access generation instruction address to an address pin of the microprocessor. An emulator device includes the above microprocessor device and a hold circuit, connected to the address pin in the microprocessor, for holding the data output from the microprocessor through the address pin. An address signal line is connected to the hold circuit. A trace memory stores the information transferred through the address pin as trace information during a real-time trace operation. A trace control circuit generates the selection signal and the hold signal to the hold circuit and generates a store signal. The hold circuit outputs the operand address to the address signal line when the hold signal and the selection signal are in the enable state.

    摘要: In a data processing apparatus, when making an access to a specific object to be accessed, the data processor supplies an access control signal to a plurality of control signal generators. The data processor further supplies accessed object type data to the accessed object type determining circuit. The determining circuit determines the type of the accessed object on the basis of the accessed object type data, and selectively drives the control signal generator corresponding to the accessed object. The control signal generator driven converts the access control signal into a control signal adapted for the accessed object. An address signal and data are transferred between the specific accessed object supplied with this control signal and the data processor via the address bus and data bus.

    摘要: The logic circuit is disclosed. Even if the system is stopped while an output latch circuit is in the latching state, when an input latch circuit is latching an input signal, the logic gate remains in the precharge mode, whereas the precharge signal as generated by a precharge signal generator circuit is in the "H" level, i.e. a precharge level. Therefore, the logic output from the logic gate is never erased. Within a period that the input and output latch circuits are both in the latching state, the system can be stopped without erasing the logic output.

    摘要: A digital information transfer apparatus includes N shift registers (1 through N) for storing digital information supplied to and from N respective function modules, and a common bus connected to the shift registers for parallel transfer of digital information. The shift registers are serially connected by a scan path to form a large scale shift register. An error detector in the transferring control circuit detects a failure on the common bus, and supplies a serial output signal of the Nth shift register to the 1st shift register. The processing circuit of the 1st function module rotates the contents of the 1st to Nth shift registers, through the scan path.

    摘要: In an address multiplexing apparatus for multiplexing address data to be supplied to 64K bit, 256K bit, and 1M bit DRAMs, upon multiplexing of address data, input address data of 20 bits are classified into two groups, i.e., the lower 16 bits and the upper 4 bits. The lower 16-bit group is multiplexed so that the upper 8 bits serve as row address data, and the remaining lower 8 bits serve as column address data. In the upper 4-bit group, adjacent bits are multiplexed. The apparatus can be commonly used for the three memories having different capacities with the simple circuit arrangement, and page mode access can be executed.

    摘要: A multi-level priority interrupt system is used for controlling the access of input/output control devices to a host computer which is connected to the devices and controls their operation. The input/output control devices each of which is contained on a different LSI chip, output different levels of interrupt requests to the host computer. During operation, each input/output control device outputs an interrupt signal of a frequency determined by a level of an interrupt to be sent to the host computer. The interrupt signal is supplied from one external terminal of the input/output control device. Upon receipt of the interrupt signals, the host computer determines a priority of the interrupt from the frequency of the signal and then executes a corresponding interrupt routine.
