IPC: G06F9/45
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To obtain an efficient sequence of arithmetic logic unit(ALU) instructions for performing integral multiplication by generating a look-up table containing an instruction sequence for performing multiplication by a compiler. SOLUTION: All ALU instruction codes which are usable on given architecture for calculating an integral multiplication result is listed first (S200). The instruction codes are classified into instruction codes having three operands and instruction codes having two operands (S210). Further, the former instruction codes are reserved as monitor instructions marking the end of the sequence of ALU instructions (S220). Then a range of three-operand instruction codes having two inputs and one output is recorded (S230). When the development of a 64-bit integer into the ALU instruction sequence is performed (S240), one usable input is added by levels. Once all possible codes are known (S260), an integer can be developed into the ALU instruction sequence.

Abstract: PURPOSE:To eliminate the round of a gear pump or a motor and to raise the volumetric efficiency of the same, by reducing the thickness of a seal block at its middle portion so that it is deflected by the function of high-pressure oil, and thereby compensating the clearance between the seal block and side plates or bushes. CONSTITUTION:In the inner surface of a seal block 26, there are formed arcuate surfaces 29, 30 which serve as sealing surfaces for the tooth tips of two gears 16, 17. A groove 31 and a thin part 32 are formed at the middle part of the seal block 26, i.e., at the boundary of the arcuate surfaces 29 and 30. The seal block 26 is supported in a body 13 by means of a pair of side plates 33 having the same form. With such an arrangement, when high-pressure oil is introduced into a high-pressure area 28, the seal block 26 is urged onto the tooth tips of the two gears 16, 17, so that the contact parts can be sealed positively. Further, since the thin part 32 is deflected by the function of the high-pressure oil and the clearance between the seal block 26 and side plates 33 is compensated, it is enabled to increase the volumetric efficiency of the pump or motor, and at the same time, to eliminate the sound of the same.

Abstract: PROBLEM TO BE SOLVED: To eliminate poorness by displaying a picture signal at a central part in the horizontal and vertical directions of a screen when a picture signal with a capacity less than a display capacity of a display device is displayed. SOLUTION: A division circuit 31 measures an active period length of an enable signal indicating an effective period of a picture signal. A 1st horizontal register 32 holds a half of the value measured by the division circuit 31 until an end of an active period of the next enable signal. Next, a 1st horizontal comparison circuit 33 generates a pulse signal indicating the central position of the active period when a time length from the beginning of the active period of the enable signal agrees with the value held by the 1st horizontal register 32.  And, a 4th horizontal comparison circuit 40 generates a horizontal start signal indicating a display start position in the horizontal direction when a value measured by a 2nd horizontal counter 34 reaches a length obtained by subtracting a half value of a horizontal physical length of a display area from the value measured by the 1st horizontal register 32.
