Abstract: A method and apparatus for block partition are disclosed. If a cross-colour component prediction mode is allowed, the luma block and the chroma block are partitioned into one or more luma leaf blocks and chroma leaf blocks. If a cross-colour component prediction mode is allowed, whether to enable an LM (Linear Model) mode for a target chroma leaf block is determined based on a first split type applied to an ancestor chroma node of the target chroma leaf block and a second split type applied to a corresponding ancestor luma node. According to another method, after the luma block and the chroma block are partitioned using different partition tress, determine whether one or more exception conditions to allow an LM for a target chroma leaf block are satisfied when the chroma partition tree uses a different split type, a different partition direction, or both from the luma partition tree.

Abstract: A system and method are provided for operating a pool of workers within a distributed computing system, wherein each of multiple computers host one or more workers. Each computer also hosts ledgers for one or more originators of tasks that are submitted to the pool for processing. A ledger identifies tasks from the corresponding originator that have been submitted to the pool and that have not yet been completed. When an originator submits a new task, the system (e.g., a coordinator) identifies a maximum number of concurrent tasks permitted the originator and determines, with reference to the originator's ledger, whether the task can be submitted to the pool without exceeding the limit. If so, the task is assigned to an idle worker (if any) and is added to the originator's ledger. After completion, the task is removed from the ledger. Obsolete or stale entries are periodically purged from originators' ledgers.

Abstract: A motor drive system includes an electric motor, a drive circuit and a control unit. The drive circuit provides a driving current to the electric motor. A current command generator of the control unit generates a current command according to a torque command and a motor operating information. The driving current is converted into a d-axis current and/or a q-axis current by the control unit. Consequently, the driving current is close to the d-axis current command and/or the q-axis current command corresponding to the current command. If a value of the torque command is positive, the current command generator generates the corresponding current command according to a MTPA lookup table. If the value of the torque command is negative, the current command generator generates the corresponding current command according to a zero recycle lookup table.
