Operation

Instructions That Can Be

Described Simultaneously

Notes 1, 2

Parallel load/store

ro = *dpx_mod roâ = *dpy_mod ro â *dpx, roâ â *dpy

âââ

ro = *dpx_mod *dpy_mod = rh ro â *dpx, *dpy â rh

*dpx_mod = rh ro = *dpy_mod *dpx â rh, ro â *dpy

*dpx_mod = rh *dpy_mod = rhâ *dpx â rh, *dpy â rhâ

Notes 1, 2, 3

Partial load/store

dest = *dpx_mod

dest â *dpx,

destâ = *dpy_mod

destâ â *dpy

dest = *dpx_mod

*dpy_mod = source

dest â *dpx,

*dpy â source

*dpx_mod = source

dest = *dpy_mod

*dpx â source,

dest â *dpy

*dpx_mod = source

*dpy_mod = sourceâ

*dpx â source,

*dpy â sourceâ

Direct addressing

Note 4

load/store

dest = *addr

*addr = source

dest â *addr

*addr â source

Immediate index

Note 5

load/store

dest = *dp_imm

*dp_imm = source

dest â *dp

*dp â source

dest = rl

dest â rl

Note 6

transfer

rl = source

rl â source

Immediate value setting rl = imm

rl â mm

(where imm = 0 to 0xFFFF)

dp = imm

(where imm = 0 to 0xFFFF)

dp â imm

dn = imm

(where imm = 0 to 0xFFFF)

dn â imm

dm = imm

(where imm = 1 to 0xFFFF)

dm â imm

Notes 1. Of the two mnemonics, either or both can be described.

2. After transfer, modification specified by mod is performed.

3. dest, destâ = {ro, reh, re, rh, rl}, source, sourceâ = {re, rh, rl}

4. dest = {ro, reh, re, rh, rl}, source = {re, rh, rl}, addr = {0: X-0xFFFF: X (X memory), or 0: Y-0xFFFF: Y

(Y memory)}

5. dest = {ro, reh, re, rh, rl}, source = {re, rh, rl}

6. Select any of the registers (except the general-purpose registers) as dest and source.
