2.5.3 DSP Operation Instruction Set
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 transfer 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.
B field data operation instructions are divided into three: double data operation instructions,
conditional single data operation instructions, and unconditional single data operation instructions.
The formats of the DSP operation instructions are shown in table 2.32. The respective operands
are selected independently from the DSP registers. The correspondence between DSP operation
instruction operands and registers is shown in table 2.33.
