Abstract: Provided is a simply structured multiprocessor system which equally distributes access performance for accessing a shared memory among plural master units accessing the shared memory. The multiprocessor system includes plural master units PU0 and PU1 each of which issues an access request for accessing the shared memory, a bus IF unit 4-10 which accesses a bus by a split transaction scheme and separately executes a request phase for accepting the access request; and a transfer phase for executing data transfer in response to the accepted access request. In the case where one of the master units consecutively issues plural access requests without an interval of a predetermined time period, the bus IF unit 4-10 restricts the number of consecutive transfer phase executions corresponding to the plural access requests to be not more than N.

Abstract: In a biped robot control system, stereoscopic images captured by CCD cameras are analyzed, the analyzed images are then utilized to detect presence of any moving object around the robot and if it present, to calculate moving object information, and based on the calculated moving object information, it is determined whether or not walking of the robot needs to be stopped. If it is determined to be stopped, the robot is controlled to stop within a period that brings the travel distance at stopping (distance moved between image capture by the CCD cameras and stopping of robot walking) to within a predetermined distance. With this, when the robot approaches a moving object during walking, it can be stopped within the predetermined distance to avoid collision with the moving object.

Abstract: In a moving object detection system, an edge image is generated from captured images taken by CCD cameras and a moving object distance image indicative of a distance to a moving object (such as a human being) is generated by extracting pixel corresponding thereto. Then, pixels in the moving object distance image are summed to generate a histogram and a profile extraction region is set in the moving object distance image with its center line focusing on a position whose histogram is greatest, while the edge image is superposed on the moving object distance image to correct the center line of the profile extraction region such that the moving object is detected by extracting its profile in the region. With this, it becomes possible to detect the moving objects respectively even when the two or more objects are present in neighborhood.
