Shift Right

Bitwise right shift on an integer signal: out = in >> shift. Logical mode fills with zeros; arithmetic mode preserves the sign bit (divide-by-2^shift for signed integers).

Parameters

Name	Label	Type	Default	Units	Description
shift	Shift	int	1	—	Number of bit positions to shift right.
arithmetic	Mode	enum (logical (zero-fill) / arithmetic (sign-extend))	0	—	0 = logical right shift (zero-fill from the left). 1 = arithmetic right shift (sign-bit replicated, preserves sign of negative numbers).
