• Conditional Operations and Data Transfer
• Assignment of NOPX and NOPY Instruction Codes
R01UH0083EJ0400 Rev. 4.00
Sep 21, 2010
Some instructions belonging to this class can be executed conditionally, as described earlier.
The specified condition is valid only for the B field of the instruction, and is not valid for data
transfer instructions for which a parallel specification is made. Examples are shown in figure
3.7.
When there is no data transfer instruction to be parallel-processed simultaneously with a DSP
operation instruction, an NOPX or NOPY instruction can be written as the data transfer
instruction, or the instruction can be omitted. The instruction code is the same whether an
NOPX or NOPY instruction is written or the instruction is omitted. Examples of NOPX and
NOPY instruction codes are shown in table 3.20.
