ZHANG Lei， ZHAO Yang （The30th InstituteofCETC，Chengdu 610041，China）

Abstract： Incertainembedded devices，especiallythe central node devices of star-shaped network structures，there is a necessitytomanageavastamountofinterconnectedend-userdata.Efcientindexingofspecifedend-userdataisparticularly crucial.As thenumberof interconnectedend-users grows，theindexofspecifeddatabegins toimpacttheoverallprforanceof theembedded devices.This paper presents an effcient index methodforlarge-volumedatabasedonthe CPU+FPGAhardware architecture，whichoperates independentlyoflargedatabase management software.Byestablishinganindex table betwenthe CPUandFPGAthatmaps data toadress，the methodenablesrapidretrievalandprocessngofspecifeduserdatafromalarge volumeof user data， thereby reducing latency and enhancing deviceperformance.
