Embodiment Construction
[0014] The specific embodiment of the present invention provides a kind of DDR2SDRAM controller, such as figure 1 shown, including:
[0015] The control module 1 is used to provide corresponding control signals to the initialization module 2 and the configuration module 3, receive the feedback of the control signals, and send sequential instructions to the execution module 5, determine the conversion of the operating state, and provide a state indication signal for the system;
[0016] The initialization module 2 is used for initializing the DDR2SDRAM controller and the DDR2SDRAM and setting the registers according to the control signal of the control module 1;
[0017] The configuration module 3 is configured to configure, control and indicate the states of the DDR2SDRAM controller and the DDR2SDRAM according to the control signal of the control module 1;
[0018] Data channel module 4, used to modulate and demodulate read and write data, and provide data for DDR2 SDRAM and ...
