← (m) + n4 + CY

← AR + 1

← IX + 1

(r)

← (r) – (m)

(m)

← (m) – n4

(r)

← (r) – (m) – CY

(m)

← (m) – n4 – CY

(r)

← (r) ∨ (m)

(m)

← (m) ∨ n4

(r)

← (r) ∧ (m)

(m)

← (m) ∧ n4

(r)

← (r) ∨ (m)

(m)

← (m) ∨ n4

CMP

← 0, if (m) ∧ n = n, then skip

CMP

← 0, if (m) ∧ n = 0, then skip

(m) – n4, skip if zero

(m) – n4, skip if not zero

(m) – n4, skip if not borrow

(m) – n4, skip if borrow

→ CY → (r)b3 → (r)b2 → (r)b1 → (r)b0
