Entity comm_scramble

Block Diagram of comm_scramble

The LFSR computation is unrolled to generate an arbitrary number of mask bits in parallel. The mask are output in little endian. The generated bit sequence is independent from the chosen output width.

Generics

Name	Type	Default	Description
GEN	bit_vector		Generator Polynomial (little endian)
BITS	positive		Width of Mask Bits to be computed in parallel in each step

Ports

Name	Type	Direction	Description
clk	std_logic	in	Clock
set	std_logic	in	Set LFSR to value provided on din
din	std_logic_vector	in
step	std_logic	in	Compute a Mask Output
mask	std_logic_vector	out
