we will get an SRAM chip and connect it to the kit, it isn't already on board...
so u suggest SRAM instead of on board DDR just to avoid the controller part...okay, thanks alot
to access DDR SDRAM u need DDR controller, its access is different from basic SRAM access. U cant just connect SRAM in the place of ur DDR. If u r going to have a small memory space u can write a HDL code to implement RAM inside ur FPGA. it seems ur application is small so there are two choices...
1> u can use a microcontriller and SRAM.
2> u can use FPGA and u can create SRAM inside ur FPGA which will be still compact. but this depends on the FPGA and ur memory requirements.
that board vendor will be provided with manual and some code like DDR-SRAM controller just use that code and proceed further.. you will be provided with manual saying the address for SDRAM and data and address port..
