Instruction Overview
12-4
ADSP-BF53x/BF56x Blackfin Processor Programming Reference
~ (NOT One’s-Complement)
General Form
dest_reg = ~ src_reg
Syntax
Dreg
= ~
Dreg
;
/* (a)*/
Syntax Terminology
Dreg
:
R7–0
Instruction Length
In the syntax, comment (a) identifies 16-bit instruction length.
Functional Description
The NOT One’s-Complement instruction toggles every bit in the 32-bit
register.
The instruction does not implicitly modify the
src_reg
. The
dest_reg
and
src_reg
can be the same D-register. Using the same D-register as the
dest_reg
and
src_reg
would explicitly modify the
src_reg
.
Flags Affected
The NOT One’s-Complement instruction affects flags as follows.
•
AZ
is set if the final result is zero, cleared if nonzero.
•
AN
is set if the result is negative, cleared if non-negative.
