Constrained　Model　Predictive　Control　(CMPC)　has　been　proved　to　be　a　successful　tool　in　process　industry.　With　its　excellent　tracking　performance　and　natural　ability　in　handling　constraints,　this　technique　now　expands　its　applications　to　high　band　embedded　systems.　To　make　it　more　suitable　for　hardware　implementation,　this　paper　presents　an　effective　online　computation　scheme　for　CMPC　with　interior　point　method.　Such　a　computation　scheme　is　verified　to　be　effective　and　reliable　in　FPGA　implementation　for　embedded　applications.
