  • Patent number: 11164318
    Abstract: Provided are an image recognition apparatus, an image recognition method, and a program for enabling recognition of many kinds of objects with high precision. An overall recognition unit executes, for at least one given object, a process of recognizing the position of the object in an image. A partial image extraction unit extracts, from the image, a partial image which is a part of the image associated with the recognized position. A partial recognition unit executes a process of recognizing what is one or more objects represented by the partial image, the one or more objects including an object other than the given object the position of which is recognized.

  • Patent number: 8266621
    Abstract: In an information processing system, when a request for execution of a new task is accepted, one or more of the required processing time and bus bandwidth for the new task are identified. A total required processing time, which is a sum of processing times required for the new task and a task reserved on a scheduler for indicating a procedure pertaining to a plurality of tasks, is compared with a processing time available in an apparatus executing those tasks. Similarly, a total required bus bandwidth, which is a sum of bus bandwidths required for processing the reserved task and the new task, is compared with a bus bandwidth available in the apparatus. Based on the result of the comparisons, it is determined whether the new task is executable.

  • Patent number: 8060679
    Abstract: Requestors acquire tokens before issuing access requests to a memory controller. The access requests issued are accumulated in a command queue of the memory controller. When the amount of access requests accumulated in the command queue is smaller than or equal to a first threshold, or in level 0, tokens are generated at a rate equivalent to 200% of a bus bandwidth. If the amount of accumulation is greater than the first threshold and is smaller than or equal to a second threshold, i.e., in level 1, tokens are generated at a rate equivalent to the bus bandwidth. If the amount of accumulation exceeds the second threshold, the token generation is stopped.

  • Patent number: 7617344
    Abstract: Requestors issue access requests to a memory controller. The access requests issued are accumulated in a command queue of the memory controller. When the amount of access requests accumulated in the command queue is smaller than or equal to a threshold, a free pass (FP) is granted to specified requesters. When issuing access requests, requesters request and acquire tokens before issuing the access requests if they have no FP granted. If the requesters have an FP, they simply issue the access requests.
