DIV

DIVIDE INTEGERS. Divides the contents of

DEST, SRC

the destination long-integeroperand by the

DIV

lreg, waop

contents of the source integer word operand,

(11111110) (100011aa) (waop) (lreg)

using signed arithmetic. It stores the quotient

into the low-order word of the destination

(i.e., the word with the lower address) and the

remainder into the high-order word. The

following two statements are performed

concurrently.

(low word DEST) ← (DEST) / (SRC)

(high word DEST)

← (DEST) MOD (SRC)

DIVB

DIVIDE SHORT-INTEGERS. Divides the

DEST, SRC

contents of the destination integer operand

DIVB

wreg, baop

by the contents of the source short-integer

(11111110) (100111aa) (baop) (wreg)

operand, using signed arithmetic. It stores the

quotient into the low-order byte of the

destination (i.e., the word with the lower

address) and the remainder into the high-

order byte. The following two statements are

performed concurrently.

(low byte DEST) ← (DEST) / (SRC)

(high byte DEST) ←

(DEST) MOD (SRC)

DIVU

DIVIDE WORDS, UNSIGNED. Divides the

DEST, SRC

contents of the destination double-word

DIVU

lreg, waop

operand by the contents of the source word

(100011aa) (waop) (lreg)

operand, using unsigned arithmetic. It stores

the quotient into the low-order word (i.e., the

word with the lower address) of the

destination operand and the remainder into

the high-order word. The following two

statements are performed concurrently.

(low word DEST) ← (DEST) / (SRC)

(high word DEST)

← (DEST) MOD (SRC)
