Title: Pipe-line control system
Inventor: ASAKAWA GAKUO
IPC: G06F9/38
Filed: 1992-07-21
Abstract: PURPOSE:To provide a pipe-line control system in which the performance of a calculation system can be improved by reducing the delay of a pipe-line processing. CONSTITUTION:Address information obtained by an instruction code is held in an address information holding means 1, and the address information obtained by the instruction code or the information held in the address information holding means is selected by a selecting means 2. A register interference detecting means 3 detects a register interference by the output of the selecting means 2. When the register interference is detected, the interlock of a register interference waiting is operated by a interlock means 4. And also, the interlock of the register interference waiting is operated not in a decode state, but in a pipe-line processing state following the decode state. Thus, the interlock can be attained only by operating the latch-up of one register, and the delay of the pipe-line processing can be reduced.

Title: Wavelength multiplexed light monitoring device
Inventor: TEJIMA MITSUHIRO
IPC: H04B10/07
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to precisely monitor respective wavelengths of wavelength multiplexed light and light intensity of respective wavelengths, and to improve the reliability by using a wavelength discrimination curve obtained by a wavelength discrimination means and converting from transmission light intensity of respective output ports into input light intensity of respective wavelengths. SOLUTION: In an array waveguide diffraction grating 13, transmission characteristics of output ports #1-#N become a Gauss functional dividing characteristic for an input from an input port. Photodetectors 17-1 to 17-N use respectively a pair, and detect the light intensity taken out to two adjacent output ports of the array waveguide diffraction grating 13, and they are compared by an operation means 18 or an logarithmic amplifier 19. The ratio between adjacent port outputs is given uniquely for a standardized frequency, and a wavelength discrimination characteristic is obtained. In the operation means 18, a transmissivity is obtained from the frequency obtained by taking the ratio between adjacent port outputs, and an input wavelength light intensity is calculated. Thus, a wavelength monitor output and a light intensity monitor output are obtained.
