Title: I/o controller
Inventor: WAKAMIYA YASUO
IPC: G06F11/00
Filed: 1984-09-03
Abstract: PURPOSE:To allow easy, secure and instant detection of an illegal access to memory in the I/O control routine by providing a detecting means which generates abnormal interrupt to the processor when an address anomaly is detected. CONSTITUTION:An under-address detector circuit 30 and an over-address detector circuit 31 compare their respectively set values with addresses on the address bus 102, when a microprocessor 10 accesses to a ROM 11 or a RAM 12 excepting the case of command fetching. Then if the respective addresses on the bus 102 are smaller or greater than the set values, the detector circuit 30 or 31 generates an under-address detection signal 300 or an over-address detection signal 310, and transfers the signal to an abnormal address interrupt generation circuit 32. At this time, the circuit 32 generates an interrupt at the processor 10 through the interrupt control circuit 22 by an abnormal address interrupt request signal 320, if such an interrupt generation is permitted by the processor 10. This interrupt request is given a high priority by the circuit 22, thereby making this interrupt realizable.

Filed: 1989-07-18
Abstract: PURPOSE:To obtain a semiconductor laser capable of generating induced emission light by growing a thin buffer layer on the surface of a semiconductor layer which has engraved an uneven shape in such manner that said uneven shape may be exaggerated and growing an active layer on the surface in such a manner that the recessed section may be buried. CONSTITUTION:A diffraction grating which carries out optical distribution feedback on an active layer is formed in uneven shape in cyclic mode on one side of the active layer 7. The layer 7 is designed to change its thickness distribution in conformity with the uneven shape cyclic mode and it is provided with a semiconductor thin buffer layer 6 which faces the uneven shape formed on the layer 7. Furthermore, the layer 7 is provided with a semiconductor layer 4 which is engraved in uneven shape, facing the other side of the layer 7. The layer 6 is designed to make an epitaxial growth so as to transmit the uneven shape formed on the layer 4 which the other side of the layer 6 faces, to the uneven shape formed on the layer 7. The layer 6 includes a buffer layer 6a which emphatically reforms the recessed and projected parts in the uneven shape engraved on the layer 4. This construction prevents the generation of defects on the semiconductor structure even if the diffraction grating is formed on the active layer, which makes it possible to generate induced emission light more efficiently.

Filed: 1990-07-12
Abstract: PURPOSE:To reproduce a signal smoothly for a period when noise is in existence by providing a delay means detecting a start point and an end point of noise superimposed on an input signal, and delaying the input signal to the device to hold a level just before and just after the noise, and using the level just before and just after the noise so as to interpolate the level for the period when noise is in existence. CONSTITUTION:A counter acts like a terminal counter at a time tE and a multiplexer 809 selects an output from a latch circuit 806 as an A input of an adder subtractor circuit 810. Thus, a value subtracting '(I-D)/4' from 'D' is outputted at the output of the adder subtractor circuit 810 and appears at the output of a selection circuit 9. The multiplexer 809 selects the output of a latch circuit 811 as the A input of the adder subtractor circuit 810 after a time tF. Then the adder subtractor circuit 810 outputs a value subtracting further '(I-D)/4' from an output 'D-(I-D)/4' in the timing of a clock period just before. Thus, the noise of a part on which noise NIN is superimposed is eliminated.
