Overview

The AxiStreamBatcher firmware module takes incoming AXI stream and combines multiple sub-frames (packets) into a larger super-frame.

...

NameDescription
MAX_NUMBER_SUB_FRAME_GMax. number of sub-frames in a super-frame
MAX_SUPER_FRAME_THRESHOLD_GSets the super-frame threshold (in units of bytes) to terminate the super-frame at the end of the current sub-frame
MAX_CLK_GAP_GSets the max. number of clocks cycle between sub-frame to terminate the current super-frame
AXIAXIS_CONFIG_GDefines the AXI stream configuration and used to determine the AXI stream width from AXI_CONFIG_G.TDATA_BYTES_C
