Projektet som utvecklar det \u00f6ppna mikrok\u00e4rnan seL4 har tilldelats ACM Software System Award, som \u00e5rligen utdelas av Association for Computing Machinery (ACM), den mest ansedda internationella organisationen inom datorsystem. Utm\u00e4rkelsen ges f\u00f6r prestationer inom matematisk bevisning av systemets p\u00e5litlighet, vilket visar full \u00f6verensst\u00e4mmelse med de specificerade formella spr\u00e5ken och bekr\u00e4ftar dess beredskap f\u00f6r kritiska till\u00e4mpningar. Projektet seL4 har visat att det \u00e4r m\u00f6jligt att helt formellt verifiera p\u00e5litlighet och s\u00e4kerhet f\u00f6r industrialiserade operativsystem utan att p\u00e5verka prestanda och flexibilitet. <\/p>\n

ACM Software System Award delas \u00e5rligen ut f\u00f6r utveckling av programvarusystem som haft en avg\u00f6rande inverkan p\u00e5 branschen genom att inf\u00f6ra nya koncept eller avsl\u00f6ja nya omr\u00e5den f\u00f6r kommersiell till\u00e4mpning. Prissumman \u00e4r 35 000 US-dollar. Tidigare har ACM-priserna tilldelats projekten GCC och LLVM, samt deras grundare Richard Stallman och Chris Lattner. Andra hedrade projekt och teknologier inkluderar UNIX, Java, Apache, Mosaic, WWW, Smalltalk, PostScript, TeX, Tcl\/Tk, RPC, Make, DNS, AFS, Eiffel, VMware, Wireshark, Jupyter Notebooks, Berkeley DB och Eclipse. <\/p>\n

Arkitekturen f\u00f6r mikroarkitekturen seL4 k\u00e4nnetecknas av att man flyttar delar av k\u00e4rnans resurskontroll till anv\u00e4ndarutrymmet och till\u00e4mpar samma \u00e5tkomstkontrollmetoder f\u00f6r dessa resurser som f\u00f6r anv\u00e4ndarresurser. Mikroarkitekturen tillhandah\u00e5ller ingen f\u00e4rdig h\u00f6g-niv\u00e5-abstraktion f\u00f6r hantering av filer, processer, n\u00e4tverksanslutningar osv., utan ger endast minimala mekanismer f\u00f6r att hantera \u00e5tkomsten till det fysiska adressutrymmet, avbrott och processorresurser. H\u00f6gniv\u00e5abstraktioner och drivrutiner f\u00f6r interaktion med h\u00e5rdvara implementeras separat ovanp\u00e5 mikroarkitekturen i form av uppgifter som k\u00f6rs p\u00e5 anv\u00e4ndarniv\u00e5. \u00c5tkomsten f\u00f6r s\u00e5dana uppgifter till mikroarkitekturens resurser organiseras genom fastst\u00e4llande av regler.
