addressing mode
(foldoc) | addressing mode
1. One of a set of methods for
specifying the operand(s) for a machine code
instruction. Different processors vary greatly in the
number of addressing modes they provide. The more complex
modes described below can usually be replaced with a short
sequence of instructions using only simpler modes.
The most common modes are "register" - the operand is stored
in a specified register; "absolute" - the operand is stored
at a specified memory address; and "immediate" - the operand
is contained within the instruction.
Most processors also have indirect addressing modes, e.g.
"register indirect", "memory indirect" where the specified
register or memory location does not contain the operand but
contains its address, known as the "effective address". For
an absolute addressing mode, the effective address is
contained within the instruction.
Indirect addressing modes often have options for pre- or post-
increment or decrement, meaning that the register or memory
location containing the effective address is incremented or
decremented by some amount (either fixed or also specified in
the instruction), either before or after the instruction is
executed. These are very useful for stacks and for
accessing blocks of data. Other variations form the effective
address by adding together one or more registers and one or
more constants which may themselves be direct or indirect.
Such complex addressing modes are designed to support access
to multidimensional arrays and arrays of data structures.
The addressing mode may be "implicit" - the location of the
operand is obvious from the particular instruction. This
would be the case for an instruction that modified a
particular control register in the CPU or, in a stack based
processor where operands are always on the top of the stack.
2. In IBM System 370/XA the addressing mode bit controls
the size of the effective address generated. When this bit
is zero, the CPU is in the 24-bit addressing mode, and 24 bit
instruction and operand effective addresses are generated.
When this bit is one, the CPU is in the 31-bit addressing
mode, and 31-bit instruction and operand effective addresses
are generated.

Operation", Chapter 5., 'Address Generation', BiModal
Addressing].

indirect addressing
(foldoc) | indirect address
indirect addressing
An addressing mode found in many processors'
instruction sets where the instruction contains the address
of a memory location which contains the address of the operand
(the "effective address") or specifies a register which
contains the effective address. In the first case
(indirection via memory), accessing the operand requires two
memory accesses - one to fetch the effective address and
another to read or write the actual operand. Register
indirect addressing requires only one memory access.
An indirect address may be indicated in assembly language by
an operand in parentheses, e.g. in Motorola 68000 assembly
MOV D0,(A0)
writes the contents of register D0 to the location pointed to
by the address in register A0.
Indirect addressing is often combined with pre- or post-
increment or decrement addressing, allowing the address of the
operand to be increased or decreased by one (or some specified
number) either before or after using it.

logical block addressing
(foldoc) | Logical Block Addressing
LBA
(LBA) A hard disk sector addressing scheme used
on all SCSI hard disks, and on ATA-2 conforming IDE hard
disks. The addressing conversion is performed by the hard
disk firmware.
Prior to LBA, combined limitations of IBM PC BIOS and
ATA restricted the useful capacity of IDE hard disks on IBM
PCs and compatibles to 1024 cylinders * 63 sectors per track *
16 heads * 512 bytes per sector = 528 million bytes = 504
megabytes. Modern BIOSes select LBA mode automatically, and
work around the 1024-cylinder BIOS limit by representing a
hard disk to the OS as having e.g. half as many cylinders and
twice as many heads. However, there is still an unbreakable
BIOS disk size limit of 1024 cylinders * 63 sectors per track
* 256 heads * 512 bytes per sector = 8 gigabytes, but modern
OSes (including Windows 9x, Windows NT and Linux) are
not affected by it, since they issue direct LBA-based calls,
bypassing the BIOS hard disk services completely.

multicast addressing
(foldoc) | multicast addressing
Ethernet addressing scheme used to send packets to devices
of a certain type or for broadcasting to all nodes. The
least significant bit of the most significant byte of a
multi-cast address is one.

physical addressing
(foldoc) | physical addressing
The low level addressing scheme used on
Ethernet. The 48-bit destination Ethernet address in a
packet is compared with the receiving node's Ethernet
address.
Compare IP address.
