An instruction set architecture is distinguished from a microarchitecture, ... the code density, was an important characteristic of any instruction set. It remained ...
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
The Sun Microsystems UltraSPARC processor is a type of RISC microprocessor.. In electronics and computer science, a reduced instruction set computer (RISC) is a computer architecture designed to simplify the individual instructions given to the computer to accomplish tasks.
The MIPS architecture has several optional extensions: MIPS-3D, a simple set of floating-point SIMD instructions dedicated to 3D computer graphics; [6] MDMX (MaDMaX), a more extensive integer SIMD instruction set using 64-bit floating-point registers; MIPS16e, which adds compression to the instruction stream to reduce the memory programs ...
An orthogonal instruction set does not impose a limitation that requires a certain instruction to use a specific register [1] so there is little overlapping of instruction functionality. [ 2 ] Orthogonality was considered a major goal for processor designers in the 1970s, and the VAX-11 is often used as the benchmark for this concept.
Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are defined in a given instruction set architecture define how the machine language instructions in that architecture identify the operand(s) of each instruction.
From a specific instruction set to abstract to its architecture is the job of architect (computer), but as a learner, one should learn its instruction set from its instruction set architecture. Wikipedians should stand on side of learners, so I go agree with that an "instruction set architecture" possesses its own "instruction set", rather than ...
