| Abstract: | Memory sharing technique of singe-chip and the dual-proted RAM IDT7132,which construct ATP'S first level, are introduced. Based on the analysis of methods for solving the collisions of dual-ported RAM in ATP'S first level, a software arbitration whcih can increase the perforemane of communication is proposed. |
