O projeto que desenvolve o microkernel aberto seL4 recebeu o pr\u00eamio ACM Software System Award, concedido anualmente pela Association for Computing Machinery (ACM), a mais autorit\u00e1ria organiza\u00e7\u00e3o internacional na \u00e1rea de sistemas computacionais. O pr\u00eamio foi atribu\u00eddo por conquistas em provas matem\u00e1ticas de confiabilidade, que atestam a total conformidade \u00e0s especifica\u00e7\u00f5es definidas em linguagem formal e reconhecem a prontid\u00e3o para uso em aplica\u00e7\u00f5es cr\u00edticas. O projeto seL4 demonstrou que \u00e9 poss\u00edvel realizar uma verifica\u00e7\u00e3o formal completa da confiabilidade e seguran\u00e7a para projetos de sistemas operacionais industriais, alcan\u00e7ando isso sem comprometer o desempenho e a versatilidade. <\/p>\n

O pr\u00eamio ACM Software System Award \u00e9 anualmente entregue por inova\u00e7\u00f5es no desenvolvimento de sistemas de software que impactaram significativamente o setor, introduzindo novos conceitos ou explorando novas \u00e1reas de aplica\u00e7\u00e3o comercial. O valor do pr\u00eamio \u00e9 de 35 mil d\u00f3lares americanos. Em anos anteriores, o pr\u00eamio ACM foi concedido a projetos como GCC e LLVM, e seus fundadores Richard Stallman e Chris Lattner. Al\u00e9m disso, projetos e tecnologias como UNIX, Java, Apache, Mosaic, WWW, Smalltalk, PostScript, TeX, Tcl\/Tk, RPC, Make, DNS, AFS, Eiffel, VMware, Wireshark, Jupyter Notebooks, Berkeley DB e Eclipse tamb\u00e9m foram homenageados. <\/p>\n

A arquitetura do microkernel seL4 se destaca pela desloca\u00e7\u00e3o de partes para o gerenciamento de recursos do n\u00facleo para o espa\u00e7o do usu\u00e1rio e a aplica\u00e7\u00e3o das mesmas ferramentas de controle de acesso para esses recursos, assim como para os recursos do usu\u00e1rio. O microkernel n\u00e3o oferece abstra\u00e7\u00f5es de alto n\u00edvel prontas para o gerenciamento de arquivos, processos, conex\u00f5es de rede, etc.; em vez disso, fornece apenas mecanismos m\u00ednimos para o controle de acesso ao espa\u00e7o de endere\u00e7amento f\u00edsico, interrup\u00e7\u00f5es e recursos do processador. Abstra\u00e7\u00f5es de alto n\u00edvel e drivers para interagir com hardware s\u00e3o implementados separadamente sobre o microkernel na forma de tarefas executadas no n\u00edvel do usu\u00e1rio. O acesso dessas tarefas aos recursos dispon\u00edveis do microkernel \u00e9 organizado atrav\u00e9s da defini\u00e7\u00e3o de regras.
