Memory Usage

[santosh_mg]

Hi..

I use custom built "player" software (which uses direct X) to display bitmap images as a movie sequence. Since the size of these bmp files r enormously huge(~3 gig) and the video memory obviously can't support this, I thought of adding more memory to the system (Now it has 4gig memory in it) so that it can load it into system memory itself.

However, after loading abt 2gig, the player is crashing!!

ANY clues?

Thanks,

Santosh

Question 1: Why are you using bitmaps?

Question 2: What is this coded in, and what did you use to compile it?

It sounds to me like you aren't using 32bit addressing.

I'm not 100% sure but I have had similar issues when rendering large scenes in windows. Doesn't the OS reserve about half the system memory for itself, even if not currently in use? I thought I read that somewhere once, but like I said earlier I'm not sure.

Hi

I generated and compiled the bitmaps in Pascal.. I use it as the visual stimuli for some experiments.. and I'm almost certain, the "player" uses 32 bit addressing..


Guess this is best I could do being a biologist!!

Is there any way to restrict OS from gobbling memory!??
