The core of the Real-time systems and embedded systems system is a microkernel whose reactivity (interrupt handling as in synchronous reactive programs) and proactivity (task General Terms scheduling as in traditional RTOSs) are fully programma- Languages ble. The microkernel, which we implemented on a Strong- ARM processor, consists of two interacting domain-specific Keywords virtual machines, a reactive E (Embedded) machine and a proactive S (Scheduling) machine. The microkernel code (or Real Time, Operating System, Virtual Machine microcode) that runs on the microkernel is partitioned into E and S code. E code manages the interaction of the system 1.

3S Ägare Hutchison Presenterar INQ1 - Facebookmobil Till Lågt Pris
2008-11-13 11:04 CET 3s ägare Hutchison presenterar INQ1 - facebookmobil till lågt pris 3s ägare Hutchison Whampoa tar nu upp konkurrensen med Sony Ericsson och Nokia och börjar tillverka egna mobiler under namnet INQ. Den första modellen, som presenteras idag, kombinerar Facebook med ett lågt pris. I början av nästa år kommer den att finnas i Sverige. INQ ska inte konkurrera med avancerade smartphones som Apple iPhone, Sony Ericsson X1 eller Nokia N96. I ställer har Hutchison Whampoa valt att rikta in sig på resten av marknaden, de 90 % som vill kunna använda Internet i mobilen precis som på datorn men som inte vill betala en förmögenhet för mobilen för att göra detta. Därför ska INQ tillverka mobiler där det är lätt att använda Internettjänster och som samtidigt är billiga. - INQ erbjuder en helt ny användareupplevelse på mobilen. Vi vill ta de tjänster som människor lärt sig älska på nätet och bygga in dem rakt in i hjärtat på våra mobiler. Borta är alla besvärliga inställningar. Vi gör det lika enkelt att följa dina vänner via Facebook som det är att ringa ett vanligt telefonsamtal, säger Frank Meehan, VD för INQ. - Vi är lyckliga över samarbetet med INQ och väldigt imponerade över vilken bra facebookupplevelse det blir i INQ1. Just nu har vi omkring 15 miljoner mobila facebookanvändare. Antalet har fördubblats de senaste 6 månaderna och vi hoppas att det kommer att öka ändå snabbare tack vare INQ, säger Mark Zuckerberg, koncernchef på Facebook. Förutom Facebook har INQ1 Skype med fria skypesamtal till 360 miljoner människor världen över, Windows Live Messenger och musiktjänsten Last.fm inbyggda. -
