Texas Instruments TMS320C67X/C67X+ DSP - Manual (Page 61)

3-1 Instruction Set SPRU733
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.
