This arithmetic operation device includes a first product-sum operator, a second product-sum operator, and a cumulative unit. The first product-sum operator performs a product-sum operation of input data and a first weight. The second product-sum operator is connected to an output portion of the first product-sum operator, and performs a product-sum operation of the output of the first product-sum operator and a second weight. The cumulative unit sequentially adds the output of the second product-sum operator.

Abstract: A wiring body includes: a resin portion composed of a resin material and a linear conductor portion composed of a conductive material and disposed on the resin portion. The resin portion includes: a flat portion; a protruding portion disposed corresponding to the conductor portion and protrudes towards the conductor portion with respect to the flat portion; and a recessed portion disposed between the flat portion and the protruding portion and dented into a shape of a curve in a direction away from the conductor portion with respect to the flat portion. The conductor portion includes: a contact surface in contact with the protruding portion and a top surface positioned on a side opposite to the contact surface. The top surface is parallel to the flat portion and a side surface of the protruding portion and the recessed portion are continuous.

Abstract: Data transfer between processors is efficiently performed in a multiprocessor including a shared cache memory. Each entry in a tag storage section 220 of a cache memory holds a reference number field 224 in addition to a tag address field 221, a valid field 222, and a dirty field 223. The reference number field 224 is set in a data write, and the value thereof is decremented after each read access. When the value of the reference number field 224 is changed from “1” to “0”, the entry is invalidated without performing a write-back operation. When the cache memory is used for communication between processors in the multiprocessor system, the cache memory functions as a shared FIFO, and used data is automatically deleted.

The mesh-like electrode layer includes an intersection region intersecting the fine wires with each other and a non-intersection region corresponding to a region except for the intersection region. A depression recessed toward the adhesive layer is formed in the intersection region.
