【Abstract】 In the internet of vehicles industry，massive data receiving，storage and calculation programs need a largeamount of cache area to store temporarydata.This paper presents an embeddedcache system thatconforms to the characteristicsof this scenario，which utilizes the operating system cache area and physical disk outside the localized program memory to improvethe localized data caching capability.Thecontentof this paper mainly includesthe industry solution，theconceptand advantagesof embedded cache system，the implementation principleand ideas，thedefinition of data structure，the application senarioand soon.In practical application，thesystem can efectively solve the extra costanddevelopment dificultycausedbythe traditional program temporarycache data，andcanefectively use the virtual memory of the operating system， so as to play the best performance.
