Instruction Compatibility

The C62x, C64x, and C67x DSPs share an instruction set. All of the instruc-
tions valid for the C62x DSP are also valid for the C67x and C67x+ DSPs. The
C67x DSP adds specific instructions for 32-bit integer multiply, doubleword
load, and floating-point operations. Table A−1 lists the instructions that are
common to the C62x, C64x, C67x, and C67x+ DSPs.
