Instruction Overview

Vector MAX

General Form
dest_reg = MAX ( src_reg_0, src_reg_1 ) (V)
Syntax
Dreg = MAX ( Dreg , Dreg ) (V) ;

Syntax Terminology
:
Dreg R7–0
Instruction Length
In the syntax, comment (b) identifies 32-bit instruction length.
Functional Description
The Vector Maximum instruction returns the maximum value (meaning
the largest positive value, nearest to 0x7FFF) of the 16-bit half-word
source registers to the
The instruction compares the upper half-words of
and returns that maximum to the upper half-word of
src_reg_1
It also compares the lower half-words of
returns that maximum to the lower half-word of
concatenation of the two 16-bit maximum values.
The Vector Maximum instruction does not implicitly modify input val-
ues. The
dest_reg
registers. Doing this explicitly modifies that source register.
