A processing system including a memory, command sequencers, accelerators, and memory banks. The memory stores program code including instruction threads sequentially listed in the program code. The command sequencers include a master command sequencer and multiple slave command sequencers. The master command sequencer executes the program code including distributing the instruction threads for parallel execution among the slave command sequencers. The instruction threads may be provided inline or accessed via inline thread line pointers. Each accelerator is available to each command sequencer in which multiple command sequencers may access multiple accelerators for parallel execution. The memory banks are simultaneously available to multiple accelerators. The master command sequencer may perform implicit synchronization by waiting for completion of simultaneous execution of multiple instruction threads. A command sequencer arbiter may arbitrate among the command sequencers. A memory bank arbiter may arbitrate among the accelerators for accessing the memory banks.

A method and circuit for a data processing system provide a hardware accelerator repeat control instruction (A) which is executed with a hardware accelerator instruction (B) to extract and latch repeat parameters from the hardware accelerator repeat control instruction, such as a repeat count value (RPT_CNT), a source address offset value (ADDR_INCR0), and a destination address offset value (ADDR_INCR1), and to generate a command to the hardware accelerator () to execute the hardware accelerator instruction a specified plurality of times based on instruction parameters from the hardware accelerator instruction by using the repeat count value to track how many times the hardware accelerator instruction is executed and by automatically generating, at each execution of the hardware accelerator instruction, additional source and destination addresses for the hardware accelerator from the repeat parameters until the hardware accelerator instruction has been executed the specified plurality of times by the hardware accelerator.

A method and apparatus for handling outstanding interconnect transactions between a master device and an interconnect component. For example, a transaction intervention module coupled to an interconnect component and a master device of the interconnect component. The transaction intervention module is arranged to receive an indication of a functional state of the master device. If the master device is indicated as being in a faulty functional state the transaction intervention module is further arranged to determine whether any interconnect transactions initiated by the master device with the interconnect component are outstanding. If it is determined that at least one interconnect transaction initiated by the master device is outstanding, the transaction intervention module is arranged to finalize the at least one outstanding interconnect transaction with the interconnect component.

A method for detecting a video signal that represents an image sequence and exhibits linewise repeated video data comprises selecting a plurality of line groups each having a first, a second and a third line, which originate from two consecutive fields in the case of a field sequence and from one field in the case of a frame sequence. The method determines for each line group a first line-distance measure for a difference between video contents of the first and second lines and a second line-distance measure for a difference between video contents of the second and third lines. The method then interprets the first and second line-distance measures with regard to the presence of a significant difference between these line-distance measures.

In a method and device for determining motion vectors that are each coordinated with individual regions of an image, the image is divided into a number of first main blocks, making use of a first block raster, and a first estimation process is performed to provide each first block with a motion vector. The image is also divided into a number of second main blocks, making use of a second block raster, whose position is displaced relative to or offset from the first block raster, for example in the horizontal and vertical directions, and a second estimation process is performed to provide each second main block with a motion vector. A number of subblocks are formed, each subblock being formed by an overlap region between one of the main blocks of the first raster and certain ones of the second main blocks of the second raster. A motion vector for each subblock is generated, this motion vector depending on the motion vectors of the main blocks and being coordinated with the particular subblock.

Using selected test vectors, an image comparison is performed to supply an image comparison result for each selected test vector. The selected test vectors and at least one prediction vector are compared to provide at least one test vector comparison result for each selected test vector. The image comparison result and the at least one test vector comparison result are linked to provide at least one quality characteristic for each selected test vector. A ranking order is determined for these quality characteristics, where at least one test vector is selected as the displacement vector based on the ranking order determined.

Next, an interval specified by video information values of the first pixel and the second pixel or an interval specified by video information values of the third pixel and the fourth pixel is determined and the video information values are mixed such that the video information value of the pixel to be interpolated lies within this interval.
