TMS320C1x/C2x/C20x/C5x Instruction Set Comparison

A.2 Enhanced Instructions

An enhanced instruction is a single mnemonic that performs the functions of

several similar instructions. For example, the enhanced instruction ADD

performs the ADD, ADDH, ADDK, and ADLK functions and replaces any of

these other instructions at assembly time. For example, when a program using

ADDH is assembled for the ’C20x or ’C5x, ADDH is replaced by an ADD

instruction that performs the same function. These enhanced instructions are

valid for TMS320C2x, TMS320C20x, and TMS320C5x devices (not

TMS320C1x).

Table A–2 below summarizes the enhanced instructions and the functions that

the enhanced instructions perform (based on TMS320C1x/2x mnemonics).
