英文摘要：

A high efficient and parallel access memory structure is proposed. The architecture adopts the method of ＂ logical sharing, physical distribution＂ and parallel storage of multiple memory blocks, which realizes the parallel access of 4 x 4 video array processors. The experimental results show that the proposed architecture can support simultaneous read/write operations of 16 light nuclear processing elements, the highest frequency is 200 MHz, access to the peak bandwidth of 6. 25 GB/s. Finally, the 8X 8 two-dimensional discrete cosine transform algorithm is mapped and compared. It is found that the cluster memory structure can provide data storage bandwidth of 312.2 Msamples/s. Compared with the same type of array structure, the number of execution cycles decreased 31.67%, frequency doubled, memory bandwidth is increased by 192. 60%.
