raddsp_axis_iq_magnitude

Use Cases

AXI-Stream datapath integration where module boundaries need explicit ready/valid behavior.
Reusable FPGA DSP pipelines that need fixed-point, timing-aware implementation.
Memory-mapped control/status integration with software-visible register maps.

Generics

Name	Type	Default	Description
VENDOR	string	"xilinx"	Selects the vendor-specific implementation path, usually XILINX for DSP48/XPM-backed builds or generic for portable RTL.
DEVICE_FAMILY	string	"generic"	Identifies the target FPGA family so wrappers can choose the correct primitive or conservative portable behavior.
DATA_WIDTH	positive	16	Sets the bit width for DATA WIDTH values carried by this module.
MAG_WIDTH	positive	32	Sets the bit width for MAG WIDTH values carried by this module.

Ports

Name	Direction	Type	Description
m_axis_tvalid	out	std_logic	Output AXI-stream valid qualifier for the current result beat.
m_axis_tready	in	std_logic	Output AXI-stream ready input from the downstream block.
m_axis_tdata	out	std_logic_vector(MAG_WIDTH - 1 downto 0)	Output AXI-stream payload containing packed processed result lanes.
m_axis_tlast	out	std_logic	Output AXI-stream frame marker aligned with the processed result beat.
s_axis_tvalid	in	std_logic	Input AXI-stream valid qualifier for the current sample beat.
s_axis_tready	out	std_logic	Input AXI-stream ready response indicating this block can accept a beat.
s_axis_tdata	in	std_logic_vector((2 * DATA_WIDTH) - 1 downto 0)	Input AXI-stream payload containing packed sample or feature lanes.
s_axis_tlast	in	std_logic	Input AXI-stream frame marker for the final beat of a frame.
clk	in	std_logic	Clock for the associated synchronous logic and handshake domain.
rst	in	std_logic	Active-high synchronous reset for this clock domain.
