Never heard of it - all I can think of is OpenGL :-) S29_GL_128N > I'm not sure if cache is an option with this device - but would it > make a difference anyway? Well the first read takes 100ns (plus the other chipset overhead 300ns) but other reads in a page are only an extra 25ns each. So your benefit is not from having the entire executable in cache it's from having the next 7 instructions in the cacheline for only an extra 25ns each instead of 400ns. > Interesting, thanks.

Usually these things can be fixed in the bootloader or by hacking the kernel to tweak the relevant chipset registers. -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
