Table 1. Encryption Egress Segmented AXI4-Stream Interface Signal Descriptions
Port Name Clock Domain I/O Description
enc_egr_axis_tdata<M>[127:0] enc_egr_axis_clk O Encryption Egress AXI Segment <M> Data:

Byte 0 of data on this segment is mapped to bits [7:0] and byte 15 is mapped to bits [127:120].

enc_egr_axis_tid[5:0] enc_egr_axis_clk O Encryption Egress Channel ID:

This signal represents the channel ID of the data presented on encryption egress AXI4-Stream bus. This signal is valid only in the channelized mode.

enc_egr_axis_tuser_ena<M> enc_egr_axis_clk O Per-segment enable.
enc_egr_axis_tuser_eop<M> enc_egr_axis_clk O Segment End-of-Packet indicator:

Only valid for enabled segments.

enc_egr_axis_tuser_err<M> enc_egr_axis_clk O Egress Segment Error Indicator:

This signal indicated that the packet ending on segment <M> had error indicator set when entered the core.

enc_egr_axis_tuser_mty<M>[3:0] enc_egr_axis_clk O Segment Empty Bytes indicator:

Only valid for enabled EOP segments.

enc_egr_axis_tuser_sop<M> enc_egr_axis_clk O Segment Start-of-Packet indicator:

Only valid for enabled segments.

enc_egr_axis_tvalid_<N> enc_egr_axis_clk O Standard AXI Valid:

This signal validates entire encryption egress AXI4-Stream bus for Port <N>.

  1. <N> is the port number 0 to 3 and <M> is the segment number 0 to 7.
