相变存储器离散地址数据写入读出控制系统设计

采用传统系统受到干扰信号影响,控制能力变差,提出设计一种基于可编程逻辑阵列方式的相变存储器离散地址数据写入读出系统,可改善控制能力。选用Xilinx公司的Spartan-6芯片作为配置基础,设计抗干扰可编程逻辑阵列主—被动配置方案,促使硬件具有抵抗信号干扰的能力,以该方案对电路进行连接;将硬件主—被动配置软件功能进行设计,以时序图来展示控制结果,可抵抗外界信号造成的干扰。通过实验结果得出,该系统最低控制能力也可达到80%,即使在强信号干扰下,也能对离散地址数据写入与读出进行有效控制。

Design of read out control system for variable memory discrete address data writing

The traditional system is affected by the interference signal and the control capability is worse. It is proposed to design a discrete address data write in readout system based on programmable logic array, which can improve the control ability. Using Spartan-6"s Xilinx chip as the basic configuration, programmable logic array and passive configuration scheme of anti-jamming design, the hardware has the ability to resist the interference signal, the scheme of the hardware circuit are connected; the main passive configuration software function design, with sequence diagram to show the result of control, can resist external interference signal the. The experimental results show that the minimum control ability of the system can also reach 80%. Even under strong signal interference, it can effectively control discrete address data writing and reading.
