Hardware Based Ethernet Audio And Video Bridging (EAVB) Packet Scheduling - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240113986 titled 'Hardware Based Ethernet Audio And Video Bridging (EAVB) Packet Scheduling

Simplified Explanation

The abstract describes an automobile network device with a descriptor sorting engine that uses a DMA controller, FIFO memories, a timer, and sorting logic to reorder timestamp-pointer pairs for efficient data processing.

• The device includes a DMA controller that pulls timestamp-pointer pairs from unsorted descriptor ring memory.
• The timestamp-pointer pairs are stored in FIFO memories and sorted in ascending order by the sorting logic component.
• The sorted pairs are used to read packet descriptors from the unsorted memory and store them in a sorted descriptor ring memory.

Original Abstract Submitted

various embodiments include an automobile network device that includes a descriptor sorting engine (dse). the dse may include a direct memory access (dma) controller, a memory organized by channel clusters that each include a plurality of first-in first-out (fifo) memories, a timer, and a time stamp (ts) sorting logic component. the dma controller may be configured to pull timestamp-pointer pairs from packet descriptors stored in an unsorted descriptor ring memory, store the timestamp-pointer pairs in the fifo memories, trigger the ts sorting logic component to reorder the timestamp-pointer pairs in the fifo memories so that they are sorted in ascending order, use the sorted timestamp-pointer pairs in the fifo memories to read the packet descriptors stored in an unsorted descriptor ring memory, and store the packet descriptors in a sorted descriptor ring memory.
