L4 is a family of second-generation microkernels, generally used to implement Unix-like operating systems, but also used in a variety of other systems. L4, like its predecessor L3, was created by German computer scientist Jochen Liedtke as a response to the poor performance of earlier microkernel-based operating systems. Liedtke felt that a system designed from the start for high performance, rather than other goals, could produce a microkernel of practical use. His original implementation in hand-coded Intel i386-specific assembly language code in 1993 sparked off intense interest in the computer industry. Since its introduction, L4 has been developed for platform independence and also in improving security, isolation, and robustness.

  • L4 ist der Name einer Familie von Mikrokerneln, basierend auf Konzepten und ersten erfolgreichen Implementierungen von Jochen Liedtke (daher L4).
  • L4 とは、マイクロカーネルの種類。
  • L4 - architektura mikrojądra stworzona przez nieżyjącego już Jochena Liedtke, z implementacjami na x86 (oryginalne L4 i Fiasco) oraz MIPS i Alpha. Mikrojądra oparte na L4 są znacznie bardziej wydajne od mikrojąder rodziny Mach. Istnieją korzystające z L4 modyfikacje popularnych jąder monolitycznych, m.in. oparte na Linuksie L4Linux i Wombat. Planowano również przeniesienie GNU Hurd na L4.
  • L4 — микроядро второго поколения, разработанное Йохеном Лидтке (нем. Jochen Liedtke (англ.); немецкий учёный; 1953‑2001) в 1993 году. Архитектура микроядра L4 оказалась успешной. Было создано множество реализаций ABI и API микроядра L4. Все реализации стали называть семейством микроядер L4. Реализация Лидтке неофициально была названа «L4/x86».
  • L4是一種微内核构架的作業系統内核,最初由約亨·李德克(Jochen Liedtke)设计,前身為L3微內核。在最开始,L4只是一个单一的产品,一个由約亨·李德克设计并实现的,在Intel i386上高度优化内核。L4这个微内核系统由于其出色的性能和很小的体积而开始被计算机工业所认知。随后,系统在多个方向上有了高速的发展,值得提及的是一个更加独立于硬件平台的版本,被称为Pistachio。,之后又被移植到了许多不同的硬件构架上。现在已经形成一个微内核家族,包括Pistachio,L4/MIPS,與Fiasco。

  • L4 es una familia de micronúcleos de segunda generación basada en los diseños e implementaciones originales del informático alemán Jochen Liedtke. Originalmente implementada en código ensamblador altamente afinado para procesadores Intel i386, la API ha sufrido grandes desarrollos en varias direcciones, tanto buscando un nivel más alto de independencia de plataforma como mejorando seguridad, aislamiento y robustez. Ha habido varias reimplementaciones de la interfaz binaria del núcleo L4 (ABI) y sus sucesores de más alto nivel, incluyendo L4Ka::Pistachio (Uni Karlsruhe), L4/MIPS (UNSW) y Fiasco (TU Dresden). Por esta razón, el nombre L4 ya no se refiere únicamente a la implementación original de Liedtke, sino que se aplica a toda la familia de micronúcleos que incluyen la interfaz del núcle
  • L4 est un micronoyau de seconde génération conçu par Jochen Liedtke (en). Les micronoyaux du début des années 1990 étant extrêmement lents par rapport à leurs concurrents monolithiques, Liedtke décide de développer ses propres micronoyaux. Il développe ainsi ses micronoyaux L3 et ensuite L4. Les nombreuses améliorations apportées à ceux-ci et leurs successeurs ont depuis permis d'accroître considérablement la vitesse de ces anciens noyaux pour en arriver ensuite aux micronoyaux actuels.
  • A família L4 é uma família de micronúcleos de segunda geração baseada nos projetos e implementações originais do cientista da computação alemão Jochen Liedtke. Foi originalmente implementada como código de montagem extremamente otimizado específico do Intel i386, a interface de programação de aplicativos recebeu desenvolvimento extensivo em várias direções, ambas em obter um nível de independência de plataforma e também em melhorar a segurança, isolação e robustez. O L4 é usado em produções de .
