Vector Operations Instructions
Table C-21. Vector Operations Instructions (Sheet 30 of 33)
Instruction
and Version
Vector Multiply and
Multiply-Accumulate
NOTE: When issuing compatible load/store instructions in parallel with a Vector Multiply and Multi-
ply-Accumulate instruction, add 0x0800 0000 to the Vector Multiply and Multiply-Accumulate opcode.
NOTE: The ranges of these vector opcodes naturally overlaps with the component scalar Multiply and
Multiply-Accumulate opcodes. In fact, each vector opcode is the logical "OR" of the two component sca-
lar opcodes.
Dreg_even = (A0 {=, +=, or –=} Dreg_lo_hi * Dreg_lo_hi) ,
A1 {=, +=, or –=} Dreg_lo_hi * Dreg_lo_hi (IS)
