Abstract: A data processing unit is provided comprising a handling unit configured to send invocation data including the first and second operation to an execution unit to cause the execution unit to process the invocation data. The execution unit processes the data by: obtaining data from a non-local storage based on a logical source pipe of a first operation, performing the first and a second operation for portions of the data received from the logical source pipe. In response to the output of the first operation and input of the second operation referring to a logical forwarding pipe, the execution unit performs processing for a portion of the data for the first and second operation without storing the output data of the first operation in the non-local storage.

Abstract: The technology described herein facilitates parallel encoding of two groups of blocks of data of a sequence of blocks of data, whilst also facilitating the use of dependent encoding across the sequence of data blocks. This is achieved by allocating pairs of first and second groups of data blocks to separate encoding units, and determining an encoding parameter value to be used for encoding the first block of each second group of data blocks. For correct reconstruction of the image, it is ensured that a block belonging to the first group of data blocks of a pair of groups of data blocks is encoded with an encoding parameter value that will cause a decoder to use the determined encoding parameter value when decoding the first block of the second group.
