Input / Output Data Channels
ND is mapped to s_axis_data_tvalid
RFD is mapped to s_axis_data_tready
RDY is mapped to m_axis_data_tvalid
Configuration Channel
FILTER_SEL is mapped
to the filter select field of the s_axis_config_tdata bus
Drive s_axis_config_tvalid with the same signal driving
s_axis_data_tvalid.
Note: For decimation filters
s_axis_config_tvalid must be driven at the output rate.
Configuration packets are consumed at the lower output rate and if supplied at the
input rate the Configuration Channel FIFO becomes full and s_axis_config_tready is deasserted and input packets ignored.Tie s_axis_config_tlast to 0 and ignore event_s_axis_config_*.
Reload Channel
The format of the
reload channel has changed such that COEF_FILTER_SEL is now pre-pended to the reload
packet on the s_axis_reload_tdata bus.
COEF_DIN is mapped to s_axis_reload_tdata bus
COEF_WE is mapped to s_axis_reload_tvalid
COEF_LD is mapped to s_axis_reload_tlast but is now asserted at the end of a reload
packet
