Instruction Set
This chapter describes the assembly language instructions of the
TMS320C67x DSP. Also described are parallel operations, conditional
operations, resource constraints, and addressing modes.
The C67x floating-point DSP uses all of the instructions available to the
TMS320C62x™ DSP but it also uses other instructions that are specific to the
C67x DSP. These specific instructions are for 32-bit integer multiply, double-
word load, and floating-point operations, including addition, subtraction, and
multiplication.
