Instruction Overview

MIN

General Form
dest_reg = MIN ( src_reg_0, src_reg_1 )
Syntax
Dreg = MIN ( Dreg , Dreg ) ;
Syntax Terminology
:
Dreg R7–0
Instruction Length
In the syntax, comment (b) identifies 32-bit instruction length.
Functional Description
The Minimum instruction returns the minimum value of the source regis-
ters to the
dest_reg
value closest to – ∞.) The operation subtracts
and selects the output based on the signs of the input values and the arith-
metic flags.
The Minimum instruction does not implicitly modify input values. The
can be the same D-register as one of the source registers. Doing
dest_reg
this explicitly modifies the source register.
Flags Affected
This instruction affects flags as follows.
• is set if result is zero; cleared if nonzero.
AZ
• is set if result is negative; cleared if non-negative.
