  • Patent number: 6735488
    Abstract: A production process standardization system of a semiconductor device for standardizing design rules among companies and smoothening requests for semiconductor production and distribution and re-use of design assets among companies wherein standardized design rules of a semiconductor are commonly managed by a common database management server and wherein a plurality of companies acquire the standardized design rules via the Internet and design the semiconductor device according to the commonly managed design rules, a method of the same, and a storage medium storing that method.
    Type: Grant
    Filed: September 10, 2001
    Date of Patent: May 11, 2004
    Assignee: Semiconductor Technology Academic Research Center
    Inventors: Tomohiko Kadowaki, Tadahiko Nakamura
  • Patent number: 6654873
    Abstract: A processor apparatus which reduces an overhead at the time of switching processing modules and efficiently performs desired processing at a high speed, wherein desired processing is performed by prefetching a series of instructions by a main program prefetcher, pre-decoding the same by a pre-decoder, and supplying the same to a decoder and execution unit via a multiplexer. When an instruction to execute a macro command is detected in the pre-decoder, the instructions of the macro command are prefetched by a macro program prefetcher and pre-decoded in the pre-decoder. As a result, when branching to a macro command, the instructions of the macro command can be immediately supplied to an execution unit only by switching the multiplexer.

  • Patent number: 5521854
    Abstract: A power-saving control system for an MCU includes a plurality of functional portions, a switch, and a register. The functional portions includes a CPU. The switch ON/OFF-controls supply of electric power from a power supply to the respective functional portions. The register stores data for ON/OFF-controlling the switch. The switch is ON/OFF-controlled in accordance with contents of the register, thereby stopping an operational function of each functional portion in an inactive state.
