'''Virtual-8086 Mode Enhancement''' ('''VME''') är en funktion i [[x86 architecture|x86]]-kompatibla [[Central processing unit|CPU]]:er som möjliggör effektivare körning av [[DOS]]-program på moderna [[operating system|operativsystem]]. Den introducerades av [[Intel Corporation|Intel]] i mitten av 1980-talet som en del av deras dåvarande CPU-design.<br />
<br />
==Bakgrund==<br />
VME utvecklades som en respons på behovet av att köra äldre [[software|programvara]] på nyare [[hardware|hårdvara]]. Det var speciellt relevant för att köra program som ursprungligen var avsedda för 8086-processorn, en föregångare till de moderna x86-processorer.<br />
<br />
==Funktionalitet==<br />
När VME-flaggan är aktiverad, förbättras hanteringen av [[interrupt]] och [[exception handling|undantag]] i [[Virtual 8086 mode]]. Detta läge simulerar en 8086-processormiljö, vilket möjliggör körning av programvara designad för äldre processorer på nyare system.<br />
<br />
==Användning i Moderna System==<br />
Trots att tekniken har föråldrats, fortsätter VME att vara en viktig del av x86-processorer för att säkerställa kompatibilitet med äldre mjukvarusystem.<br />
