Section 3 DSP Operating Unit
Table 3.21 Variation of ALU Fixed-Point Operations
Table 3.22 Correspondence between Operands and Registers
As shown in figure 3.10, data loaded from the memory at the MA stage, which is programmed at
the same line as the ALU operation, is not used as a source operand for this operation, even
though the destination operand of the data load operation is identical to the source operand of the
ALU operation. In this case, previous operation results are used as the source operands for the
ALU operation, and then updated as the destination operand of the data load operation.
