With　the　rapid　development　of　heterogeneous　network-on-chip　(NoC),　a　vast　amount　of　shared　resources　are　integrated　into　NoC.　Intense　resource　competition　exists　between　CPUs　and　GPUs,　leading　to　congestion　and　a　decrease　in　overall　network　performance.　Reasonable　node　placement　can　minimize　network　conflicts　at　the　topology　level.　This　paper　first　discusses　the　placement　of　shared　last-level　cache　and　memory　controller,　then　selects　a　more　rational　placement　method　and　optimizes　the　path.　To　solve　the　hot　spots　problem　in　center　placement　method,　a　task-based　routing　algorithm　is　designed　to　plan　the　path.　Simulation　results　demonstrate　that,　compared　to　the　traditional　routing　algorithm,　the　overall　network　latency　is　reduced　by　9%,　and　the　CPU　performance　is　improved　by　13.6%.　Furthermore,　a　dynamic　task-based　routing　algorithm　is　proposed.　Compared　to　the　static　task　routing　algorithm,　the　overall　network　latency　is　reduced　by　2.08%,　and　the　CPU　performance　is　improved　by　4.09%.
