CMP.GEUI evaluates unsigned greater-than-or-equal over decoded scalar operands and publishes canonical XLEN one or zero.
The instruction snapshots its operands, prepares the decoded immediate, and then evaluates unsigned greater-than-or-equal.
uimm12 is zero-extended to XLEN before any shift or comparison.
A true relation becomes XLEN one; a false relation becomes XLEN zero.
RegDst selects the encoded destination or discard behavior.SrcL supplies the left scalar source.uimm12 supplies an unsigned encoded immediate.The canonical boolean is published through the encoded destination, then TPC advances by 4 bytes.
The instruction does not modify commit state and does not access memory or reservation state.
Encoding, reserved field values, and source availability are checked before destination, control, or TPC effects.
This example illustrates the current owner and does not create a second semantic definition.
cmp.geui SrcL, uimm, ->{t, u, Rd} publishes XLEN one when its condition is true and XLEN zero otherwise.
Bodies come from owning ASL. Dragging or buttons change only this page-session view order.
No NDF clause is attached to this unit.
