  2. Bootstrapping (compilers) - Wikipedia

    en.wikipedia.org/wiki/Bootstrapping_(compilers)

    Bootstrapping (compilers) In computer science, bootstrapping is the technique for producing a self-compiling compiler – that is, a compiler (or assembler) written in the source programming language that it intends to compile. An initial core version of the compiler (the bootstrap compiler) is generated in a different language (which could be ...

  3. Tombstone diagram - Wikipedia

    en.wikipedia.org/wiki/Tombstone_diagram

    To explain, the lefthand T is a C compiler written in C that produces machine code. The righthand T is a C compiler written in machine code that also produces machine code. The diagram illustrates that this can be used to bootstrap the left T by using it to compile the compiler written in C. In computing, tombstone diagrams (or T-diagrams ...

  4. Compiler - Wikipedia

    en.wikipedia.org/wiki/Compiler

    There are many different types of compilers which produce output in different useful forms. A cross-compiler produces code for a different CPU or operating system than the one on which the cross-compiler itself runs. A bootstrap compiler is often a temporary compiler, used for compiling a more permanent or better optimised compiler for a language.

  5. Bootstrapping (electronics) - Wikipedia

    en.wikipedia.org/wiki/Bootstrapping_(electronics)

    Bootstrapping (electronics) In the field of electronics, a technique where part of the output of a system is used at startup can be described as bootstrapping. A bootstrap circuit is one where part of the output of an amplifier stage is applied to the input, so as to alter the input impedance of the amplifier.

    AMD 22V10 in 24-pin DIP. Programmable Array Logic ( PAL) is a family of programmable logic device semiconductors used to implement logic functions in digital circuits that was introduced by Monolithic Memories, Inc. (MMI) in March 1978. [1] MMI obtained a registered trademark on the term PAL for use in "Programmable Semiconductor Logic Circuits".

  8. Optimizing compiler - Wikipedia

    en.wikipedia.org/wiki/Optimizing_compiler

    An optimizing compiler is a compiler designed to generate code that is optimized in aspects such as minimizing program execution time, memory use, storage size, and power consumption. Optimization is generally implemented as a sequence of optimizing transformations, algorithms that transform code to produce semantically equivalent code ...
