Abstract:
An apparatus for efficient parallel executing instruction avoiding the usage of cross bypasses, the apparatus including an instruction buffer for storing instructions, of decoders for decoding, in parallel, the instructions which simultaneously issue from the instruction buffer, executing units for executing the instructions decoded in the decoders, and an instruction-issuing controlling means for controlling the issuing of the instructions in such a way that, when the instructions are executed, one of the plural executing units executes instructions more frequently than the rest of the plural executing units. The apparatus is preferably incorporated in an information processor to superscalar or out-of-order instruction execution.
Abstract:
A slider is formed by a metallic main body, a synthetic resin-made frame, and a pair of end caps. The frame is detachably fitted to outer sides of the main body. Ball rolling grooves are provided in the main body. Return paths and inside grooves of a direction changing path are provided in the frame. An outside groove of the direction changing path are provided in each end cap. A paste-like filler is applied to a boundary portion between the main body and the frame and a boundary portion between the frame and the end cap, and is allowed to cure.
Abstract:
The present invention relates to a processor system. The processor system is made up of a multithread control unit for selectively making switching among said threads to be executed in an arithmetic unit, a loop predicting unit for predicting a loop of an instruction string on the basis of a processing history of a branch instruction in the thread, and a loop detecting unit for, when the loop predicting unit predicts the loop, detecting the loop on the basis of an instruction. When the loop detecting unit detects the loop, the multithread control unit making the switching from the thread, which is in execution in the arithmetic unit, to a different thread. This prevents a wait condition stemming from the loop from interfering with the execution of other threads without retouching software.
Abstract:
A cache control device comprises a command control section 43 for receiving a cache deterioration report and generating a cache flush mode initiation signal which performs degeneration of the cache 44, a software interrupt section 52 for interrupting the supply of commands from software in response to the cache flush mode initiation signal, a command generating section 53a for generating fetch requests in which cache data flushing occurs to the cache in response to the cache flush mode initiation signal, an address generating section 54 for generating addresses for flushing the cache data in response to the cache flush mode initiation signal, and a request counter 58 for specifying ways at which flushing of the cache will be performed, whereby degeneration is possible where different CPUs are mounted in the system, or where a CMP micro architecture is employed, without the necessity of changing the system hardware or OS, or making additions to the computer architecture.
Abstract:
In order to aim at shortening the time of refueling by maintaining the function of prevention of discharge of vapor, similar to that of a conventional canister in the case of other than refueling during resting of an engine while the flow resistance in the canister becomes smaller during refueling, there is provided a canister in which a plate is vertically arranged in a chamber charged therein with absorbent in the canister, and filter support pins are projected from opposite surfaces of the plate while filters are arranged at the tip end faces of the filter support pins, and in which a plurality of constriction passages are formed being arranged in a horizontal direction only in the upper part of the plate.

Abstract:
A photographic camera has a barrier which is disposed between the camera body and a decorative front cover to be movable between a closing position where it covers a taking lens of the camera and an opening position where it opens the taking lens through an opening formed in the front cover. The barrier is provided with an opening which is brought into alignment with the taking lens and the opening in the front cover when the barrier is moved to the opening position and has a smaller diameter than the opening in the front cover. An anti-flare pattern of recessed portions and protruded portions is formed on the outer surface of the barrier around the opening.
Abstract:
In a telephone set having a receiver (42) and a loudspeaker (39), a switch circuit (37) selects supply of a reception speech signal, transmitted from a counterpart section (60), to the receiver or the loudspeaker in response to a selection signal. A first adaptive echo canceller (43a) produces a pseudo echo signal with reference to the reception speech signal. A controller (44) controls operation of the first adaptive echo canceller in response to the selection signal to optimize the pseudo echo signal. A first digital adder (35a) carries out a particular calculation between the pseudo echo signal and a transmission speech signal, relating to the transmission sound supplied to a microphone (46). The adder produces a particular calculation result signal representative of a result of the particular calculation. In accordance with the particular calculation result signal, a transmission is carried out towards the counterpart section.
Abstract:
A transceiver records an identification number of a calling station included in a received control signal. The recording is done automatically in the event of unattended recording or in response to a record command during conversation. The transceiver originates a call in response to a transmission signal using the stored identification number of the calling station.
Abstract:
A gain controller for use in mobile telephone system is disclosed. It is judged whether digital input data includes speech data or not. When the digital input data includes speech data, an integration energy value of the digital speech data for a predetermined time length is measured. The measured integration energy value is compared with a higher threshold value and a lower threshold value. A step level is set to a predetermined minus value, a predetermined plus value and "0" when the integration energy value is higher than the higher threshold value, lower than the lower threshold value and within a range between the higher and lower threshold values, respectively. The obtained step level is then added to the digital speech data.
