    摘要： The present invention makes it possible to let a user arbitrarily and easily see any other scene than himself or herself in his or her view (the scene seen from any other moving body than him or her). In a display device (an image pickup and display device 1 or a display device 40), specification information is generated to specify a specific image pickup device of outer image pickup devices (the image pickup and display device 1 or and image pickup device 30), and image data are received from the image pickup device specified by the specification information and are displayed. As an outer image pickup device, for example, and image pickup device wore by some other person, image pickup devices set at a car, an electric train, and the like, or further mage pickup devices set at an animal, a bird, and the like are supposed. Image data picked up by these image pickup devices are transmitted to the display side and the image display is carried out in the display device. Thus, a user of the display device can see images of viewing scenes watched by other people, for example, images of viewing scenes seen from a car, an electric train, and the like, or images of viewing scenes seen from an animal, a bird, and the like.

    摘要： A branch prediction apparatus to minimize branch penalties in pipeline or concurrent processing of a sequence of instructions correctly predicts a pattern in which “branch taken” and “branch not taken” alternately appear. The apparatus includes a branch prediction table to keep one history bit and a 2-bit counter for each branch instruction, a prediction generator to output a value of the history bit when the counter has a value of 0 or 2 and to output a value obtained by reversing the history bit when the counter has a value of 1 or 3, and a counter controller which compares a result of branch with a value of the history bit. The counter controller sets 0 to the counter value when the result matches the value and adds one to the counter value when the result does not match the value and the counter value is other than 3.

    摘要： A method, an apparatus, and a computer program are provided to more efficiently generate a sticky bit in a Floating Point Design. Traditionally, separate ORing logic or OR trees were employed to compress the stick outputs of a normalization shifter into at least one sticky bit. However, this design has power consumption and area costs associated with it. To overcome these disadvantages, the OR trees of Leading Zero Counters (CLZs) are employed in conjunction with the Edge Vector logic of a Leading Sign Anticipator and an additional OR gate to determine the sticky bit.
