专利汇可以提供Digital arithmetic device专利检索,专利查询,专利分析的服务。并且PURPOSE:To transfer data among a plurality of data processors and to speed up data processing by providing a switch which switches a flow of digital data at every connection points of a data bus from a data processor and a looped data bus. CONSTITUTION:Looped data buses 19-22 are provided with four switches 23- 26, and processors each consisting of an arithmetic logical unit 15, a register 17, a shifter 18, a selector 28, etc., are connected to the buses 19-22. When the signal line of this arithmetic device has logic 1, the switches 23 and 25 are opened to transfer the arithmetic result of an arithmetic circuit 14 to an RAM13 or the circuit 14 through the shifter 18, switch 26, selector 28, etc., and the arithmetic result of the unit 15 to the register 17 through the switch 24. When it has logic (0), the switches 24 and 26 are opened to transfer the arithmetic result of the unit 15 to the RAM13 or circuit 14 through the switch 23 and selector 28, and the arithmetic result of the circuit 14 to the register 17 through the shifter 18 and switch 25.,下面是Digital arithmetic device专利的具体信息内容。
