    摘要： In one embodiment, a processor comprises a scheduler configured to issue a first instruction operation to be executed and an execution core coupled to the scheduler. Configured to execute the first instruction operation, the execution core comprises a plurality of replay sources configured to cause a replay of the first instruction operation responsive to detecting at least one of a plurality of replay cases. The scheduler is configured to inhibit issuance of the first instruction operation subsequent to the replay for a subset of the plurality of replay cases. The scheduler is coupled to receive an acknowledgement indication corresponding to each of the plurality of replay cases in the subset, and is configured to inhibit issuance of the first instruction operation until the acknowledge indication is asserted that corresponds to an identified replay case of the subset.

    摘要： Various techniques are described to test memory arrays of a programmable logic device (PLD). In one example, a PLD includes a first memory array. The PLD also includes a plurality of sense amplifiers adapted to read a plurality of data values stored by the first memory array and provide a plurality of data signals corresponding to the data values. The PLD further includes a test circuit adapted to test the first memory array. The test circuit is coupled with the sense amplifiers and adapted to compare the data signals with a test signal to provide a pass/fail signal. In addition, the PLD includes a second memory array. The PLD also includes a data shift register adapted to test the second memory array.

    摘要： A packet transmit queue control system including a first data structure, a second data structure, a packet controller, and a port transmit controller is disclosed. The first data structure can include a plurality of linked-list data structures and can store unicast type packet pointers. The second data structure can include a plurality of first-in first-out (FIFO) structures and can store multicast type packet pointers. The packet controller can receive a first sequence of unicast and/or multicast type packets. The port transmit controller can provide a second sequence of the unicast and/or multicast type packets. Further, each of the plurality of FIFO structures can correspond to an output port of the system.

    摘要： An omni-directional robot cleaner, composed of a platform and a plurality of driving units for driving and controlling the movement of the platform, in which the platform further comprises: a sensing unit, for obstacle detection; a cleaning unit, for collecting and removing dust and dirt; a processing unit, capable of receiving signals transmitted from the sensing unit while planning and mapping a travel path accordingly; and a power unit, for providing power to the omni-directional robot cleaner while managing the same. Moreover, each driving unit of the plural driving units is comprised of an omni-directional wheel and an actuator for driving the corresponding omni-directional wheel to rotate omni-directionally, by which the platform is enabled to move continuously while changing its moving direction simultaneously so as to free the robotic cleaner from the shortcomings of those conventional autonomous cleaner, such as poor maneuverability, poor mobility and insufficient degree-of-freedom regarding to the driving of the cleaner. Therefore, not only the operation mobility of the robotic cleaner is enhanced, but also the moving agility of the same is greatly improved.

    摘要： System and method for graphically allocating robot's working space are provided. The system includes an image extractor, a task-allocating server and a robot. A graphic user interface (GUI) of the task-allocating server includes a robot's working scene area, a space attribute allocating area and a robot's task area. Thus, a user assigns one certain space area in the robot's working scene area with a “wall” attribute, or another space area with a “charging station” attribute. Meanwhile, by using the GUI, the user directly assigns the robot to execute a specific task at a certain area. Hence, the user or remote controller facilitates the robot to provide safer and more effective service through his/her environment recognition.

    摘要： In one embodiment, a processor comprises a retire unit and a load/store unit coupled thereto. The retire unit is configured to retire a first store memory operation responsive to the first store memory operation having been processed at least to a pipeline stage at which exceptions are reported for the first store memory operation. The load/store unit comprises a queue having a first entry assigned to the first store memory operation. The load/store unit is configured to retain the first store memory operation in the first entry subsequent to retirement of the first store memory operation if the first store memory operation is not complete. The queue may have multiple entries, and more than one store may be retained in the queue after being retired by the retire unit.
