This disclosure concerns a semiconductor circuit design method for designing a clock wiring structure supplying a clock to a flip-flop by using a computer. The semiconductor circuit design method comprises setting the flip-flop based on circuit information on a semiconductor integrated circuit; obtaining a control signal controlling the flip-flop; calculating a first evaluation value indicating a power consumption and a magnitude of a clock skew time when clock gating is applied to the flip-flop; setting a gated clock structure clock-gating the flip-flop when the first evaluation value is higher than a first threshold; calculating a second evaluation value indicating the power consumption and a magnitude of a cell area when a low power flip-flop lower in power consumption than the flip-flop is applied to the flip-flop; and replacing the flip-flop by the lower power flip-flop when the second evaluation value is higher than a second threshold.

A radio communication terminal includes a link-usage level calculating section that calculates usage level of a radio link, and a data reception continuation/suspension determining section that determines continuation of data reception or suspension of data reception according to the level of usage calculated by the link-usage level calculating section. The link-usage level calculating section calculates a current usage level indicating a level of usage of the radio link associated with current data reception in the radio communication terminal. The data reception continuation/suspension determining section determines continuation of data reception when the current usage level is equal to or higher than a reference level of usage being a threshold and determines suspension of data reception when the current usage level is lower than the reference level of usage.

Ascochlorin or an analog or derivative thereof and a compound having a primary amino group are mixed and reacted with each other in the presence/absence of a basic catalyst to synthesize a novel imino compound. The novel imino compound thus synthesized is a ligand capable of activating nuclear receptor superfamily such as retinoid orphan receptor (RXR), peroxisome proliferator-activated receptor (PPAR) and steroid receptor (PXR), and shows an effect of promoting the transcription of a drug-metabolizing enzyme CYP7A1. The imino compound has a therapeutic effect on diseases such as lifestyle-related diseases, chronic inflammation and cancers.

The computer aided design for clock gated logic circuits is conducted by extracting, by the use of information about a clock gated logic circuit under the design, a halt condition under which a clocked circuit driven by a clock signal can halt with no clock signal supplied, generating enable signal candidates, from a halt condition, which can be used as enable signals in the clock gated logic circuit, analyzing the clock gated logic circuit in order to obtain information about a delay time of signal transmission and electric power consumption reduction if respective one of enable signal candidates is used as an enable signal of a clock gating circuit inserted in the clock gated logic circuit under the design, storing enable signal candidate information including the result of the analysis conducted by an analysis step in an information store, selecting an appropriate one of the enable signal candidates which satisfy given restrictions regarding a delay time of signal transmission in the clock gated logic circuit under the design, by the use of enable signal candidate information; and adding the clock gating circuit activated with the enable signal as selected by enable signal selection step to the clock gated logic circuit under the design.
摘要:
An instruction flow control circuit controls the selection and execution of instruction signals in a microprocessor having multiple execution units that can execute plural instructions at one time. The instruction flow control circuit compares a number of signals indicating how many execution units are available with a number of signals indicating how many execution units are required. The circuit is a matrix of transmission gates which propagate signals through, or shift signals between, various signal paths for available resources, depending on the signals requesting the executing units. A number of output gates suppress the execution of instruction signals where an execution unit is requested but none are available.
