1.1 English

When s_axis_video_tvalid is asserted, no interface signals (except the Sensor Demosaic core driving s_axis_video_tready ) can change value until the transaction completes ( s_axis_video_tready , s_axis_video_tvalid , and AP_RST_N are High on the rising edge of AP_CLK ). When asserted, s_axis_video_tvalid can only be deasserted after a transaction has completed. Transactions cannot be retracted or aborted. In any cycle following a transaction, s_axis_video_tvalid can either be deasserted or remain asserted to initiate a new transfer.
