    摘要： A microcomputer that can process plural tasks time-divisionally and in parallel, wherein one of a plural programs described by one of the tasks is described as a looped specific task in which the increment of program addresses is fixed, a program counter is usable as a timer counter, a peripheral function instruction is described in the specific task, the peripheral function instruction is set so as to indicate one or more general-purpose registers as an operand. The CPU executes the peripheral function instruction as one instruction and achieves information needed to execute the instruction by a general-purpose register and stores the execution result into the general-purpose registers. An instruction code encoding system includes an operation code and plural operands for indicating operation targets of an instruction in an instruction code and executing an instruction indicated by the operation code on the operation targets. When the operation targets indicated by the plural operands are set to a combination in which an execution result does not vary, the processing corresponding to an instruction different is executed.

    摘要： Disclosed is a photonic switch that includes a plurality of optical-path switching means having movable light reflecting portions that guide light from each of a plurality of input ports to any output port among a plurality of output ports. Each of the optical-path switching means is made to produce a specific loss so as to reduce path-to-path variations in loss along the paths from the input to the output ports. Specifically, loss along a path is the total of loss based upon optical path length and loss produced by the optical-path switching means. A specific loss is produced by each of the optical-path switching means in such a manner that total loss is equalized from path to path.
