how to access memory through fpga

[vani_pat]

Hi All,

In my project I needed to access the image data coming from camera that will be stored in the on-board memory that has to be accessed by FPGA and then finally it is to be displayed on the PC. My queries are:-
1. How to access the data stored on the on-board memory by FPGA?
2. Then how to process and make changes on that data as per our need?

Please Kindly consider my queries its urgent.

1. Interface the memory using a controller. It depends on: memory type (SRAM, SDRAM, DDR, DDR2, etc), then there are several posibilities:
a) Write Your own memory controller.
b) Use the available ipcore (opencore or bought one)
c) Use special tool made by Your FPGA vendor. E.g. Xilinx offers MIG.

2. Thats kind of a stupid question. Process data as You need, do some logic to solve Your tasks.

The most important part: learn how to ask a question first, then learn how to use google and finally, learn everything else.
