The problem of reading the data of the memory

[Altera_Forum]

hello! 

i know the address of memory and i want to read the data. for example: i know the address of SDRAM is 0x01000000, what should i do to read the data from the SDRAM.   thanks in advance.

Do you use a SDRAM controller? 

Do you want to access it from a CPU or from custom hardware?

[Altera_Forum]

yes i have a sdram controller; 

i want to read the data from the address through the application. thank you very much.

You can use C pointers for that. 

Do you also use the sdram to store the software itself? In that case you'll have to use a memory allocation function, such as malloc(), to allocate a memory area. If not, you can just get the address and size of your memory area from system.h.
