memory - Finding RAM product/solution for tiny embedded linux system (<1GB) -


i'm finding quite difficult navigate among copious memory solutions available when selecting ram solution tiny embedded system i'm developing.

i run os such petalinux on zynq-7000 soc , nothing more 32 mb required this. additionally, run simple graphical user interface on small touch screen.

this battery powered device , don't want excessive resources on board because of space , energy consumption. feel few gb of ram might unnecessary. don't want utilise soon-to-be obsolete technology either.

  1. are there energetic downsides having excessive ram or these negligible?
  2. for lasting technologies, ddr3 sdram optimal choice?
  3. how ram types deviate in energy consumption?

any guidance highly appreciated!

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
