Section 3 DSP Operating Unit
3.5.13
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.
Table 3.34 Correspondence between Operands and Registers
Notes: 1. Registers available for operands
There are three cases of operand conflict problems.
• When ALU operation and multiply instructions specify the same destination operand (Du and
• When X-memory load and ALU operation specify the same destination operand (Dx and Du,
• When Y-memory load and ALU operation specify the same destination operand (Dy and Du,
In these cases above, the result is not guaranteed.
