LEON (from Spanish: león meaning lion) is a radiation-tolerant 32-bit central processing unit (CPU) microprocessor core that implements the SPARC V8 instruction set architecture (ISA) developed by Sun Microsystems. It was originally designed by the European Space Research and Technology Centre (ESTEC), part of the European Space Agency (ESA), without any involvement by Sun. Later versions have been designed by Gaisler Research, under a variety of owners. It is described in synthesizable VHSIC Hardware Description Language (VHDL). LEON has a dual license model: An GNU Lesser General Public License (LGPL) and GNU General Public License (GPL) free and open-source software (FOSS) license that can be used without licensing fee, or a proprietary license that can be purchased for integration in a

  • LEON és una Unitat Central de Procés RISC de 32 bits de . És SPARC V8 (1987) (compatibles, i dissenyat per Gaisler Research i l'Agència Espacial Europea. Està modelitzat amb el llenguatge de descripció de maquinari VHDL disponible sota la GPL. (ca)
  • LEON est un processeur 32 bit RISC libre, compatible SPARC V8 (1987) développé par l'ingénieur suédois Jiri Gaisler pour répondre aux besoins de l'Agence spatiale européenne (processeurs endurcis pour les contraintes spatiales) en garantissant l'indépendance de l'Europe. Il est utilisé par des satellites et des lanceurs développés par l'Europe. Il est téléchargeable sous licence LGPL (version 2) et GPL (version 3). Une version tolérante aux erreurs (« Fault Tolerant », implémentant une détection d'erreurs permettant son usage en conditions de radiations élevées) est aussi accessible pour LEON3. (fr)
  • LEON è un microprocessore RISC a 32 bit. Il processore è compatibile a livello di istruzioni con i processori SPARC V8 (specifiche 1987) ed è stato sviluppato dalla e dalla Agenzia Spaziale Europea. Il processore è sintetizzato con il linguaggio VHDL ed è disponibile sotto GNU General Public License. (it)
  • LEON - mikroprocesor programowy napisany w języku VHDL. Jest dostępny jako open source na licencji GNU LGPL. Posiada 32 bitową architekturę RISC. LEON jest zgodny z architekturą programową SPARC-V8 i jest rozwijany przez firmę oraz Europejską Agencję Kosmiczną. Istnieje kilka wersji tego procesora, w tym wersja odporna na awarie stosowana w krytycznych systemach kosmicznych. (pl)
  • LEON — 32-битное микропроцессорное ядро, созданное на базе архитектуры SPARC V8. Изначально разрабатывалось в Европейском центре космических исследований и технологий (ESTEC), подразделении Европейского космического агентства (ЕКА), затем компанией Gaisler Research. Оно написано на языке VHDL, код предоставлен в свободное использование по лицензии GNU General Public License для LEON3 и GNU Lesser General Public License для LEON1 и LEON2. Также возможно лицензирование под коммерческой лицензией. Ядро имеет много параметров конфигурации и может быть использовано для построения систем на кристалле как для коммерческих так и для некоммерческих применений. (ru)

  • LEON ist eine Familie von 32-Bit-Prozessoren, basierend auf der SPARC-V8-Architektur. Ursprünglich entworfen von der ESA, wird das Prozessordesign heute von Aeroflex Gaisler weiterentwickelt und vertrieben. Der LEON war das erste unter einer Open-Source-Lizenz veröffentlichte vollständige Mikroprozessor-Design, die LEON-Prozessoren sind verfügbar als VHDL-Designs zur Verwendung zum Beispiel in FPGAs oder ASICs.
