Filed: 1987-11-24
Abstract: PURPOSE:To save the hardware remarkably in comparison with conventional technology with the constitution of n-set of mXm optical matrixes for the highway switch by constituting the highway switch in a large capacity wavelength multiplex optical switch by m-set of acoustooptical elements as basic components. CONSTITUTION:The output light of primary optical highways 3-1-3-m is collimated by collimating lenses 10-1-10-m and inputted to acoustooptical elements 11-1-11-m. The elements 11-1-11-m are driven by a signal being the result of the signal superimposed with electric signals of frequencies f1-fn by a superimposition circuit M. Then the optical signal of wavelengths lambda1-lambdan to be inputted is diffracted in a direction of thetaij=lambdaifj/v (v is sound velocity of acoustooptical medium) independently of the frequencies f1-fn. Thus, the diffracted light is collected by condenser lenses 12-1-12-m, then the light is made incident in an optical channel of waveguide arrays 13-1-13-m.

Title: Direct memory access controller
Inventor: SAKUMA HIROYA
IPC: G06F13/28
Filed: 1989-11-15
Abstract: PURPOSE:To increase the processing speed of a direct memory access DMA controller by stopping the DMA operation and outputting a stop signal when the coincidence is obtained between the data under transfer and the retrieving data set at the starting time point. CONSTITUTION:The desired data to be retrieved in a DMA transfer mode is set to a data comparator 2 before execution of the DMA transfer. The compara tor 2 performs the comparison between the data on a data bus 7 with the set comparison data at reception of a read/write strobe signal 8. When the coinci dence is obtained between both data, a control signal 9 is changed to an L level from an H signal. The DMA request signal 10 is discontinued by an AND gate 3 and an L level is inputted to a DMA controller. Thus, the DMA transfer is stopped. At the same time, the signal 9 of an L level outputs a signal of an H level to an interruption controller 6 via a NOT gate 11. Then a microcom puter 5 restarts the DMA transfer. In such a constitution, the processing speed is increased with the DMA controller.
