Orthogonal Instruction Set - Orthogonality in Practice - The VAX-11
0 - 255, and each operand consisting of two nibbles, the upper 4 bits specifying an addressing mode, and the lower 4 bits (usually) specifying a register number (R0 - R15) ... This resulted in 16 logical addressing modes (0-15), however, addressing modes 0-3 were "short immediate" for immediate data of 6 bits or less (the 2 low-order ... 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 ...
Reduced Instruction Set Computing - Characteristics and Design Philosophy - Hardware Utilization
... are separate floating point registers) Simple addressing modes, with complex addressing performed via sequences of arithmetic and/or load-store operations Few data types in hardware ... take advantage of features intended to facilitate manual assembly coding, and that complex addressing modes take many cycles to perform due to the required additional ... Another general goal was to provide every possible addressing mode for every instruction, known as orthogonality, to ease compiler implementation ...
Obsolete Addressing Modes
... The addressing modes listed here were used in the 1950–1980 time frame, but are no longer available on most current computers ... there have been many other interesting and peculiar addressing modes used from time to time, e.g ...
PDP-11 Architecture - Addressing Modes - Stack Addressing Modes
... A convention enforced by the set of modes the PDP-11 provided is that a stack grew downward—toward lower addresses—as items were pushed onto it ... When a mode is applied to SP, or to any register the programmer elects to use as a software stack, the addressing modes have the following effects Code Name Example Description 16 ...

Famous quotes containing the words modes and/or addressing:

    In the final analysis, “style” is art. And art is nothing more or less than various modes of stylized, dehumanized representation.
    Susan Sontag (b. 1933)

    But what is quackery? It is commonly an attempt to cure the diseases of a man by addressing his body alone. There is need of a physician who shall minister to both soul and body at once, that is, to man. Now he falls between two stools.
    Henry David Thoreau (1817–1862)
