Can FPGA Stratix 3 memory handle large amount of data?

I need to allocate an array in FPGA of 20 elements, each of size 323 bits, but don't know if my fpga memory can handle this size.

I am using an FPGA Stratix 3. I hav tried looking up on the intel website : https://www.intel.com/content/www/us/en/programmable/products/boards_and_kits/dev-kits/altera/kit-siii-host.html, but i couldn't understand exactly which part described the memory size.

I might have 2 ways to do it : either allocate an array of 20 elements of 323 (= 17*19) bits, or a matrix of 20*19 elements of 17 bits each (which means 20*19 variables). But i don't know which way is better. Would you have any recommendations ?

Solution

  • If you read that page you will find that the development board use the "Stratix III EP3SL150F1152" device.

    Next you have to find the information for that device. I often use digikey's website for that, their website is very good for this sort of things.
    Next you have to find the information for that device, which I admit is a bit difficult as the first four links I used where either too details (timing) or to broad (Family handbook).

    The "Family overview" is the one you need and that has a table:

    From that you can see that the EP3SL150 device has ~6.390 Kbits of memory. You need 20x323=6460 bits so your circuit will fit nearly a thousand times. (Well... at least as far as the memory goes. I don't know how much logic you need around the memory).
