13.3.4
ADD
INSTRUCTION
The ADD (Add to accumulator) instruction is used to add data to the VSP’s accumulator. Flags affected are
EQ0 and EQ1.
Table 37
ADD instruction
13.3.5
SUB
INSTRUCTION
The SUB (Subtract from accumulator) instruction is used to subtract data from the VSP’s accumulator. Flags affected
are EQ0 and EQ1.
Table 38
SUB instruction
13.3.6
MUL
INSTRUCTION
The MUL (Multiply with accumulator) instruction is used to multiply data with the VSP’s accumulator. Flags affected are
EQ0 and EQ1. The second operand of the multiplication is restricted to 16-bit; e.g. R(r.a.).
