A method of performing compression of image data for at least one image is described. The method comprises receiving image data of at least a part of the at least one image, encoding the received image data into at least one compressed data block, applying at least one bandwidth limit to the at least one compressed data block, and outputting the at least one bandwidth limited compressed data block to a buffer. The method further comprises dynamically updating the at least one bandwidth limit applied to the at least one compressed data block base at least partly on a fill level of the buffer.

Method and apparatus for performing compression of image data

A task control circuit maintains, in response to task event information, a task information queue that includes task information for a plurality of tasks. Based upon the task information in the task information queue, a future task switch condition is identified as corresponding to a task switch time for a particular task of the plurality of tasks. A load start time is determined for a set of instructions for the particular task. A pre-fetch request is generated to load the set of instructions for the particular task into the memory circuit. The pre-fetch request is forwarded to a hardware loader circuit. In response to the task switch time, a task event trigger is generated for the particular task. The hardware loader circuit is used to load, in response to the pre-fetch request, the set of instructions from a non-volatile memory into the memory circuit.

Hardware controlled instruction pre-fetching

Pre-fetching instructions for tasks of an operating system (OS) is provided by calling a task scheduler that determines a load start time for a set of instructions for a particular task corresponding to a task switch condition. The OS calls, and in response to the load start time, a loader entity module that generates a pre-fetch request that loads the set of instructions for the particular task from a non-volatile memory circuit into a random access memory circuit. The OS calls the task scheduler to switch to the particular task.

Instruction pre-fetching

A method of data streaming in a streaming system () that comprises a processor () and a controller () operably coupled to a streaming peripheral () via a shared interconnect () is described. The method comprises at the controller, receiving at least one descriptor that points to at least one header data element in memory and at least one payload buffer element in the streaming peripheral (); reading the at least one descriptor () by the controller (); fetching by the controller the at least one header data element from memory and the at least one payload element from the payload buffer () in the streaming peripheral () referred to by the descriptor ().
