Indirect and Post-Increment Index Addressing
The syntax of the form:
[Dst_1 ++ Dst_2] = Src_hi
is indirect, post-increment index addressing. The form is shorthand for
the following sequence.
[Dst_1] = Src_hi ;
ter, indirect*/
Dst_1 += Dst_2 ;
by Dst_2 */
where:
•
Src_hi
in the syntax example).
• is the memory destination pointer register on the left side of
Dst_1
the syntax.
• is the increment index register.
Dst_2
Indirect and post-increment index addressing supports customized indi-
rect address cadence. The indirect, post-increment index version must
have separate P-registers for the input operands. If a common
for the inputs, the auto-increment feature does not work.
