摘要： An apparatus for processing variable length coded data includes a coefficient buffer unit and several lookup tables. The coefficient buffer unit includes a coefficient memory and an index register for storing an indication of a non-zero nature of coefficients stored in the coefficient memory. Advantageously, the lookup tables may be altered to adapt the apparatus for processing variable length coded data to handle encoding or decoding video adhering to a specific standard. Furthermore, the lookup tables may be adapted to accelerate the determination of the presence of escape codes and the subsequent handling of the escape codes.

摘要： In a multiprocessor system, a task control processor may be placed in the path connecting each execution processor to a system bus. Such task control processors may detect the completion of a first task on an associated execution processor and, responsively, generate commands to lead to the initiation of a second task on the same, or another, execution processor. Such task completion detection and task initiation by the task control processors removes, from a central processor or the execution processors, the burden of performing such tasks, thereby improving the efficiency of the entire system.

摘要： A SIMD processor responds to a single min/max instruction to find the minimum or maximum valued data unit in an array of data units. The determined minimum/maximum value and an associated index value thereto may be output. Alternatively, the value of a data unit in another array may be output at a corresponding location. A further single instruction executable by the SIMD processor, may be applied to results obtained using such a single min/max instruction, to allow such instructions to operate on two dimensional arrays.

摘要： A single instruction, multiple data (SIMD) processor including a plurality of addressing register sets, used to flexibly calculate effective operand source and destination memory addresses is disclosed. Two or more address generators calculate effective addresses using the register sets. Each register set includes a pointer register, and a scale register. An address generator forms effective addresses from a selected register set's pointer register and scale register; and an offset. For example, the effective memory address may be formed by multiplying the scale value by an offset value and summing the pointer and the scale value multiplied by the offset value.

摘要： Methods and apparatus for encoding image data to facilitate subsequent insertion of local image data. Also methods and apparatus for inserting image data, e.g., at local broadcast stations, without having to fully decode a received encoded bitstream. The encoding methods involve treating images to be encoded as a plurality of distinct, non-overlapping image regions or segments for encoding purposes. Image segments which are designated for use for local data insertion are not used as reference data for motion compensated prediction purposes when generating motion vectors to represent image areas, e.g., the area representing the main picture, which are outside the local data insertion segments. Because image segments which may be replaced are not used as reference data for image segments which will not be replaced, unintentional prediction errors which might otherwise result from replacing one or more image segments as part of a local data insertion operation are avoided.
摘要翻译：用于编码图像数据以便于随后插入局部图像数据的方法和装置。以及用于例如在本地广播站插入图像数据的方法和装置，而不必完全解码所接收的编码比特流。编码方法涉及将图像编码为用于编码目的的多个不同的，不重叠的图像区域或片段。指定用于本地数据插入的图像段在生成用于表示图像区域（例如，表示主图像的区域）的运动矢量时不用作用于运动补偿预测目的的参考数据，其在本地数据插入段之外。由于可以替换的图像段不被用作不被替换的图像段的参考数据，因此避免了由于将一个或多个图像段替换为本地数据插入操作的一部分而导致的意外预测误差。
