Excalibur electronic A-MNL-NIOSPROG-01.1 manual Movhi, Move Immediate Into High Half-Word

32-Bit Instruction Set

MOVHI

Move Immediate Into High Half-Word

Operation:

h1RA ← (K : IMM5), h0RA unaffected

Assembler Syntax:

MOVHI %rA,IMM5

Example:

Not preceded by PFX:

MOVHI %g3,23 ; upper 16 bits of %g3 get 23

Preceded by PFX:

PFX %hi(100)

MOVHI %g3,%lo(100) ; upper 16 bits of %g3 get 100

Description:

Not preceded by PFX:

Copy IMM5 to the most significant half-word (bits 31..16) of RA. The least

significant half-word (bits 15..0) is unaffected.

Preceded by PFX:

The immediate operand is extended from 5 to 16 bits by concatenating the

contents of the K-register (11 bits) with IMM5 (5 bits). The 16-bit immediate value

(K : IMM5) is copied into the most significant half-word (bits 31..16) of RA. The

least significant half-word (bits 15..0) is unaffected.
