There are many more indirect addressing modes.
Shift-add" addressing modes common in microprocessors are not present.
CISC does not even need to have complex addressing modes;
Addressing modes for 16-bit x86 processors can be summarized by this formula.
The table above presents the first case to show different addressing modes achievable this way.
Addressing modes for 64-bit code on 64-bit x86 processors can be summarized by this formula.
In any case,both bit and word addressing modes are possible with either NOR or NAND flash.
Addressing modes for 32-bit address size on 32-bit or 64-bit x86 processors can be summarized by this formula.
Or 64-bit RISC processors may well have more complex addressing modes than small 8-bit CISC processors.
Simple addressing modes, with complex addressing performed via sequences of arithmetic and/or load-store operations;
Through the use of the Stack Pointer(R6) and Program Counter(R7) as referenceable registers,there were 10 conceptual addressing modes available.
Since the PDP-11 was an octal-oriented(3-bit sub-byte) machine(addressing modes 0-7, registers R0-R7), there were(electronically) 8 addressing modes. .
Besides instructions, the ISA defines items in the computer that are available to a program-e.g. data types,registers, addressing modes, and memory.
Others, like the PDP-11 andthe 68000 family have addressing modes that make it possible to use any of a set of registers as a stack pointer.
In computer engineering,an orthogonal instruction set is an instruction set architecture where all instruction types can use all addressing modes.
The ISA has five instruction formats and supports two addressing modes: register indirect with displacement, and program-counter relative.
In the late 1970s research at IBM(and similar projects elsewhere)demonstrated that the majority of these"orthogonal" addressing modes were ignored by most programs.
More general addressing modes Any GPR can be used as a base register, and any GPR other than ESP can be used as an index register, in a memory reference.
Depending on architecture, the operands may be register values, values in the stack, other memory values, I/O ports, etc., specified and accessed using more orless complex addressing modes.
CISC does not even need to have complex addressing modes; 32 or 64-bit RISC processors may well have more complex addressing modes than small 8-bit CISC processors.
The ARM processor also has features rarely seen in other RISC architectures, such as PC-relative addressing(indeed, on the 32-bit ARM the PCis one of its 16 registers) and pre- and post-increment addressing modes.
Supports various addressing modes including immediate, offset, and scaled index but not PC-relative, except jumps(introduced as an improvement in the x86-64 architecture).
The general-purpose registers, base registers, andindex registers can all be used as the base in addressing modes, and all of those registers except for the stack pointer can be used as the index in addressing modes.
The ARM processor also has some features rarely seen on other architectures that are considered RISC, such as PC-relative addressing(indeed, on the ARM the PCis one of its 16 registers) and pre- and post-increment addressing modes.
(The main benefit of the sib byte is the orthogonality andmore powerful addressing modes it provides, which make it possible to save instructions and the use of registers for address calculations such as scaling an index.).
This involves resource and storage decisions, such as deciding which variables to fit into registers and memory andthe selection and scheduling of appropriate machine instructions along with their associated addressing modes(see also Sethi-Ullman algorithm).
The CDC 6600 designed by Seymour Cray in 1964 used a load/store architecture with only two addressing modes(register+register, and register+immediate constant) and 74 operation codes, with the basic clock cycle being 10 times faster than the memory access time.
The addressing modes were not dramatically changed from 32-bit mode, except that addressing was extended to 64 bits, virtual addresses are now sign extended to 64 bits(in order to disallow mode bits in virtual addresses), and other selector details were dramatically reduced.
In the mid-1970s, researchers(particularly John Cocke) at IBM(and similar projects elsewhere)demonstrated that the majority of combinations of these orthogonal addressing modes and instructions were not used by most programs generated by compilers available at the time.
Since addressing modes 0-3 were identical, this made 13(electronic) addressing modes, but as in the PDP-11, the use of the Stack Pointer(R14) and Program Counter(R15)created a total of over 15 conceptual addressing modes(with the assembler program translating the source code into the actual stack-pointer or program-counter based addressing mode needed).
