Little Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.. It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a viable target for a C compiler.
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.
There is an LC (Low-Cost) version, without an FPU [5] and EC (Embedded Controller), without MMU and FPU. The 68060 design was led by Joe Circello. The 68060 design was led by Joe Circello. The 68060 shares most architectural features with the P5 Pentium .
A given instruction set can be implemented in a variety of ways. All ways of implementing a particular instruction set provide the same programming model, and all implementations of that instruction set are able to run the same executables. The various ways of implementing an instruction set give different tradeoffs between cost, performance ...
Before the RISC philosophy became prominent, many computer architects tried to bridge the so-called semantic gap, i.e., to design instruction sets that directly support high-level programming constructs such as procedure calls, loop control, and complex addressing modes, allowing data structure and array accesses to be combined into single instructions.

The MOV instructions supported all addressing modes for both parameters. [9] In contrast, the NS320xx series were originally designed as single-chip implementations of the VAX-11 ISA. Although this had to change due to legal issues, the resulting system retained much of the VAX-11's overall design philosophy and remained completely orthogonal. [10]
