题目

英语翻译
存储器控制器主要功能是协调CPU和功能IP核对外部存储器的数据交换.了解静态随机存取存储器的工作方式和控制方式,不同厂家产品的不同以及各自的操作方式.归纳出通用的时序控制方式,掌握把硬件IP行为级别进行FPGA综合、布局布线的流程和方法.是本设计的意义所在.本设计走的一条由表及里技术路线,即先对DDR3的功能进行分析,得到相关时序关系和数据传递关系,然后根据通信协议逐步深入研究控制动作的数学模型,建立数学模型与硬件结构的关系,完成硬件接口模块来配合硬件电路控制实现其功能,完成CPU和功能IP核都需要与外部存储器进行数据交换,存取数据.

答案

The memory controller is the main function of coordination of CPU and function of IP check external memory data exchange. Static random access memory operating mode and control mode of different manufacturers, different products as well as their mode of operation. Generalize common timing control mode, control the hardware IP behavior level, FPGA integrated wiring layout method and process. Design is the meaning of. The design of a technical route from the outside to the inside, namely first on DDR3function analysis, relative temporal relation and data transfer relationship, then according to the communication protocol through in-depth study on control action of mathematical model, mathematical model and hardware structure relationship, complete the hardware interface module to cooperate with the hardware circuit to control the realization of its functions, complete CPU and function of IP nucleus with an external memory for data exchange, data access.
