RSP Instruction Set Details

This appendix describes the machine-language format of the RSP
instructions and formally describes the behavior of each instruction.
Since the RSP instruction set conforms to the MIPS ISA, the format and
notation of this appendix is the same as Appendix A in the book
R4000 Microprocessor User's Manual"
Vector Unit instructions are also discussed in Chapter 3, "Vector Unit
Instructions."
In this appendix, all variable subfields in an instruction format (such as
rt, immediate
For the sake of clarity, we sometimes use an alias for a variable subfield in
the formats of specific instructions. For example, we use
format for load and store instructions. Such an alias is always lower case,
since it refers to a variable subfield.
In the instruction descriptions that follow, the
the operation performed by each instruction using a high-level language
notation.
Special symbols used in the notation are described in Table A-1, "RSP
Instruction Operation Notations," on page 152.
