Re: Re: SW4STM32 or CubeMX to init STM32 device
64 bit apps can use all of a systems memory. I have 8GB, so that means eclipse is able to run above 4GB, which can be more efficient on my system at times.
32 bit apps are stuck to the lower 4GB and as this space becomes crowded, Windows/OS X will start swapping and this leads to slower performance. I usually have some other 32 bit apps running on the system, so crowding can be an issue.
As the OS is 64 bits, that means that it lives in the upper regions of the 8GB space, thus not competing for memory space with apps. FWIW, when bit 63 is set, the system is working in Windows.
