In　order　to　improve　the　overall　throughput　of　processors,　to　increase　thread-level　parallelism　(TLP)　and　instruction-level　parallelism　(ILP)　intra　and　inter　cores,　and　ensure　the　scalability　of　multi-core　systems,　can　a　novel　mechanism　chip　multithreading　with　resource　unit　manager　(RUM-CMT)　be　used,　which　is　presented　in　this　paper.　By　introducing　the　efficiency　difference　of　resource　utilization　among　threads,　such　as,　the　condition　of　dynamically　resource　allocation　to　CMT　architecture　and　add　an　absorption　barrier　for　all　threads　to　make　their　reserved　resources　far　away　from　hidden　hunger.　For　verify　the　applicability　of　RUM-CMT,　a　4　cores　with　2　threads　processor　and　a　4　cores　with　4　threads　processor　are　simulated　based　on　GEMS　&　Simics　simulator.　And　this　limited　study　shows　RUM-CMT　can　increase　performance　by　29.79%,　and　an　improve　success　committed　instructions　per　squash　instructions　by　31.15%　and　fairness　attains　6.25%　improvements　over　static　partition　on　4　cores　with　4　threads　processor.　The　4　cores　with　2　threads　also　attains　passable　enhance.　So　RUM-CMT　can　accurately　and　concise　reallocate　resource　according　to　phase　turning　in　the　running　of　applications,　improve　resource　utilization,　mining　the　ILP　and　TLP　in　applications.　In　other　words,　RUM-CMT　improves　the　controllability　of　threads,　reduces　invalid　losses　and　improves　system　efficiency,　and　it　is　a　suitable　solution　for　multicore,　multithreaded　architecture.
