The AXI4-Stream, memory mapped AXI4, and AXI4-Lite interfaces must be
synchronous to the core clock signal ap_clk
. All
AXI4-Stream, memory mapped AXI4 interface input signals, and AXI4-Lite control interface
input signals are sampled on the rising edge of ap_clk
.
All AXI4-Stream output signal changes occur after the rising edge of ap_clk
.
