NOTE
Clock cycles shown for byte transfers For word operations add 4 clock cycles for all memory transfers
The Effective Address (EA) of the memory operand
is computed according to the mod and rm fields
if mod
e
11 then rm is treated as a REG field
if mod
e
00 then DISP e 0
disp-low and disp-
high are absent
if mod
e
01 then DISP e disp-low sign-ex-
tended to 16-bits disp-high is absent
if mod
e
10 then DISP e disp-high disp-low
if rm
e
000 then EA e (BX) a (SI) a DISP
if rm
e
001 then EA e (BX) a (DI) a DISP
if rm
e
010 then EA e (BP) a (SI) a DISP
if rm
e
011 then EA e (BP) a (DI) a DISP
if rm
e
100 then EA e (SI) a DISP
if rm
e
101 then EA e (DI) a DISP
if rm
e
110 then EA e (BP) a DISP
if rm
e
111 then EA e (BX) a DISP
DISP follows 2nd byte of instruction (before data if
required)
except if mod e 00 and rm e 110 then EA e

EA calculation time is 4 clock cycles for all modes
and is included in the execution times given whenev-

The physical addresses of all operands addressed
by the BP register are computed using the SS seg-
ment register The physical addresses of the desti-
nation operands of the string primitive operations
(those addressed by the DI register) are computed
using the ES segment which may not be overridden
