Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To increase the data processing speed of a superscalar type processor which transfers an execution result to a reorder buffer through write-back buses less than execution units. SOLUTION: Six execution units 7 to 12 are given priority levels. Each execution unit sends a request to use a write-back bus to a bus arbitration unit 14. A signal generating circuit 16 of the bus arbitration unit 14 generates signals for allocating write-back buses 17 to the execution units according to the assigned priority levels. Then a control part 15 sends an acknowledgment signal allowing the specific execution unit to use the specific write-back bus on the basis of the signal. Consequently, the execution unit transfers its execution result to the reorder buffer 3 through the acknowledged specific write-back bus 17.

Title: Color picture tube
Inventor: TOKITA KIYOSHI
IPC: H01J29/51
Filed: 1981-10-06
Abstract: PURPOSE:To omit a convergence-correcting circuit in a color picture tube having three electron guns arranged in a line, and reduce the degree of the pin-distortion correction by correcting the coma of the pattern of a central electron beam which is horizontally long and vertically short compared to the pattern of both side electron beams. CONSTITUTION:Due to magnetic bodies 15 and 16, most part of the magnetic flux of a horizontally deflecting magnetic field, which originally passes near a central electron- beam discharging hole 13, is absorbed by the first magnetic bodies 17 and 19. As a result, the intensity of the horizontally deflecting magnetic field existing around the hole 13 becomes considerably weak compared to that seen when there are no field- regulating elements. In addition, due to the focusing effect caused by the second magnetic bodies 23 and 25 and the third magnetic bodies 24 and 26, the intensity of a horizontally deflecting magnetic field existing around both side electron beam discharging holes 12 and 14 becomes considerably weak compared to that seen when there is no field-regulating elements. Consequently, the field-regulating elements 15 and 16 weaken the horizontal-deflection sensitivity of a central electron beam, and increase the horizontal-deflection sensitivities of both side electron beams, thereby enabling correction of the horizontal coma among the comae of the patterns of a color picture tube.
