2.6.4
DSP operation instructions are instructions for digital signal processing performed by the DSP
unit. These instructions have a 32-bit instruction code, and multiple instructions can be executed
in parallel. The instruction code is divided into an A field and B field; a parallel data transfer
instruction is specified in the A field, and a single or double data operation instruction in the B
field. Instructions can be specified independently, and are also executed independently. The
parallel data transfer instruction specified in the A field is exactly the same as a double data
transfer instruction. The function of the A field—that is, the data transfer instruction field—is
