Performance Optimization of Shared Main Memory System of Zhongke SoC
Zhimin Zhang · Jisuanji gongcheng · 2006
In order to reduce accessing delay of the shared main memory sub-system(MMS) of Zhong ke SoC, this paper analyzes the consistence of the timing delay by a behavior model of L*Bus. It reduces the average refuse rate and access delay of the MMS evidently by using the operation queue and the open-page memory controller in the MMS. It also presents a M/M/1/N queuing model for MMS, tests MMS and MMS_E system in the MMSITE , and the result shows that the key parameters of the MMS like accessing delay, total data read and write per second and read /write operation count per millisecond have been improved a lot after the optimization .
