  • Patent number: 11042359
    Abstract: According to the embodiments, a semiconductor device includes: an adder configured to generate positive multiple data of the multiplicand which is used for a plurality of the multiplication in plurality and does not include a value of 2n (n is a positive integer) of the multiplicand; a Wallace tree circuit provided in each of the multiplier circuits and configured to operate a sum of a plurality of partial products by using a plurality of adders; and a selection circuit provided in each of the multiplier circuits and configured to select, according to a plurality of bits selected from the multiplier, data falling in a multiple of one of the multiplicand, data of 2n of the multiplicand, and the positive multiple data from the adder in order to output as one partial product of the plurality of partial products to the Wallace tree circuit.

  • Patent number: 10602618
    Abstract: A parts mounting system includes: a parts checking section that detects parts information which is identification information applied to the electronic parts and includes a parts code for specifying parts of the electronic parts and a parts maker code for specifying the parts maker and checks the detected parts information with parts information previously registered in a storing part; and a parts data generation section that, when the detected parts information is unregistered parts information in which the parts code is stored in the storing part and the parts maker code of the parts code is not stored in the storing part, generates parts data of the electronic parts relating to the unregistered parts information based on previously registered parts data having the same parts code.

  • Publication number: 20190286562
    Abstract: According to an embodiment, an information processing apparatus includes a cache memory and a cache controller. The cache controller includes a first circuit, a second circuit and a third circuit. The first control circuit is configured to store a designated address range for a process of cache maintenance. The second circuit is configured to determine whether or not the addresses to be accessed for the cache memory by the information processing apparatus are within the designated address range. The third circuit is configured to store reservation information for reserving execution of a process of cache maintenance for cache lines corresponding to addresses within the designated address range.

  • Publication number: 20160125757
    Abstract: An operator support system includes a controller which controls a component mounting apparatus. The controller includes: an input unit which receives an operator ID; a display unit which displays an operation instruction content or an operation learning content with respect to the operator; a memory unit which stores, in correspondence with the operator ID, an operator level and display history of the operation learning content; and an arithmetic processing unit which determines, at a time of executing an operation, the operation instruction content or the operation learning content to be displayed by the display unit, based on the operator ID input into the input unit, and the operator level and the display history corresponding to the input operator ID.

  • Patent number: 6104403
    Abstract: A part model creation unit creates part models necessary for the assembly of a three-dimensional object model, in the form of three-dimensional part models having junction reference data for joining to other part models, and stores them in a part storage unit. An assembly processing unit selects at least two part models from the part storage unit for the arrangement in a work coordinate space and joins the part models together on the basis of the junction reference point data to thereby assemble a three-dimensional object model.
