Operand Conflict
When an identical destination operand is specified with multiple parallel instructions, data conflict
occurs. Table 3.34 shows the correspondence between each operand and registers.

Notes: 1. Registers available for operands
2. Registers available for operands (when there is operand conflict)
There are three cases of operand conflict problems.
• When ALU operation and multiply instructions specify the same destination operand (Du and
Dg)
• When X-memory load and ALU operation specify the same destination operand (Dx and Du,
or Dz)
• When Y-memory load and ALU operation specify the same destination operand (Dy and Du,
or Dz)
In these cases above, the result is not guaranteed.
