APPENDIX D INSTRUCTION SET LIST

D.1 Conventions

(1) Register symbols used to describe operands

reg1 General-purpose registers: Used as source registers.

reg2

General-purpose registers: Used mainly as destination registers. Also used as source register in some

instructions.

reg3

General-purpose registers: Used mainly to store the remainders of division results and the higher 32 bits

of multiplication results.

bit#3 3-bit data for specifying the bit number

immX X bit immediate data

dispX X bit displacement data

regID System register number

vector 5-bit data that specifies the trap vector (00H to 1FH)

cccc 4-bit data that shows the conditions code

sp Stack pointer (r3)

ep Element pointer (r30)

listX X item register list

(2) Register symbols used to describe opcodes

R 1-bit data of a code that specifies reg1 or regID

r 1-bit data of the code that specifies reg2

w 1-bit data of the code that specifies reg3

d 1-bit displacement data

I 1-bit immediate data (indicates the higher bits of immediate data)

i 1-bit immediate data

cccc 4-bit data that shows the condition codes

CCCC 4-bit data that shows the condition codes of Bcond instruction

bbb 3-bit data for specifying the bit number

L 1-bit data that specifies a program register in the register list
