Mem Src/Dst
Dest
Reserved bit (code as 0)
Floating-point accumulator select
Constant operands rather than register
Destination precision for vector (0 = sp, 1 = dp)
Long immediate 32-bit data
Parallel memory operation specifier
Vector store or load source/dst register
Destination register
P Destination precision for parallel load/store (0 = single, 1 = double)
P1 Precision of source1 operand
P2 Precision of source2 operand
PD Precision of destination result
RM Rounding Mode (0 = N, 1 = Z, 2 = P, 3 = M)
S Scale offset by data size
Z Use 0 rather than accumulator
