Abstract: Via use of a shared data bus, a processor system offloads processing tasks. For example, a processor system communicates over a respective data bus with a data communication controller. After notifying the data communication controller of a particular block of data to retrieve, the processor system relinquishes control of the respective data bus so that the data communication controller can control the data bus and store a block of data in a specified memory location using direct memory access techniques. Upon receiving a notification of completion of storing the data block by the data communication controller, the processor system regains control of the respective data bus and notifies a data forwarding circuit to: i) partition the block of data into data packets, ii) apply respective headers to the data packets based on the header information received from the processor system, and iii) forward the data packets to the respective destination.

Abstract: Each set of pointers inserted into a received data stream eventually includes pointer values that point to other locations (e.g., other segments) within the data stream. Initially, pointer values can be set to null values because an address or respective index to other segments or other sets of pointers in the data stream may not be known until they are either received from the live feed or inserted into the data stream. As new segments of data are received from an original data stream such as a live feed, a processing function herein backfills the null pointer values in the set of pointers with appropriate values to the newly received segments or set of pointers. Backfilling of appropriate pointer values into the data stream enables a respective user viewing the data stream to initiate navigation amongst the data stream and potentially view a live feed with little or no delay.
