| Abstract: | Aiming at the problem that memory system on chip becomes a bottleneck of improving the performance of multi-core processor as the speed distinction between CPU and memory increases. This paper analyses the design characters of memory system in multi-core processor, such as Non-Uniform Cache Access(NUCA) caused by delay, constraint to access performance of connection between core and cache, and complexity of on-chip cache design. |

| Keywords: | multi-core memory system Non-Uniform Cache Access(NUCA) |
