    摘要： A noise filter for a video processing system includes a block selector, a cost calculator, a cost table, a cost comparator, and a coefficient filter. The block selector is coupled to receive data from the quantization unit and selects blocks for additional filtering. The selected blocks are provided to the cost calculator determines a cost for each of the coefficients in the block using the cost table and the costs are summed. The cost comparator compares the total to a threshold, and filters the coefficients using the coefficient filter if the total is greater a preset threshold. The noise filter to the VLC unit then outputs the filter data.

    摘要： Video data compression requires several calculations to be made repeatedly on pixel data from the video. Some of those calculations are used to determine which way to encode portions of the video data, either to provide the best compression results or simply to comply with the MPEG specification. The present invention presents a set of calculations and logic that can be performed in parallel so that the delay is minimized in order to speed up the compression of digital video data. The present invention provides a third escape mode for use when in performing variable length coding.

    摘要： A method and a device for file transfer protocol (FTP) deadlock detection and self recovery are provided by the disclosure in order to solve the sudden deadlock problem in the FTP upload task. The method includes: if a daemon determines that a deadlock occurs in an FTP upload task by a heartbeat detection mechanism, the socket resources used by the FTP upload task is recorded at the storage location in a socket resource cycle queue, and a process of ending the FTP upload task is started; determining whether the socket resource cycle queue is full, if it is not full, the socket resources used by the FTP upload task in the current deadlock is put into the socket resource cycle queue, otherwise, the earliest socket resources in the socket resource cycle queue are released, and the socket resources used by the FTP upload task in the current deadlock is put into the socket resource cycle queue.

    摘要： A gap protection device for an examining table includes a guide rail, a protecting chain and a rigid rope. The guide rail is fixed onto the non-moving part of the examining table. One end of the protecting chain is fixed onto the body of the examining table and is movable along the guide rail so as to cover the gap between the body and the non-moving part of the examining table. The two ends of the rigid rope are respectively connected to the two ends of the protecting chain. When the examining table is moved, the closed loop formed by the protecting chain and the rigid rope circulates synchronously under the drive of the examining table, such that the protecting chain covers the gap between the body and the non-moving part of the examining table.

    摘要： A processing system includes an arithmetic logic unit (ALU) sub-system that allows data associated with a prior instruction to be preserved for use with a next instruction or subsequent instruction without having to reload the value using an intermediate register. The ALU sub-system includes a pair of ALUs communicatively cross-coupled with a pair of accumulators. The processing system also includes a data selector coupled to the ALU sub-system for use with memory contention prediction. The data selector includes a constant generator that controls storage of data associated with a previous instruction in a bypass element, and a selector to choose between data from a databus element and data stored in the bypass element.
