Event Frame Sequencer Protocol development

[ruck314]

Description

This module draws inspiration from the AxiStream Batcher Protocol Version 1, which uses the AxiStreamBatcherEventBuilder.vhd. Unlike the original design, which creates a single super-frame per event, this module transmits event frames in a guaranteed sequence. As a result, each event consists of multiple frames, but the order of these frames within an event is always preserved.

In the AxiStreamBatcherEventBuilder.vhd, a super-header and multiple sub-frame tails are prepended or appended to the stream. In contrast, this module eliminates tail appending and instead prepends a header to each frame as it is forwarded through the sequencer. This header includes all the metadata necessary to reconstruct AXI stream sideband information on the receiver side, such as TDEST, TUSER_FIRST, and other relevant signals.
