Can i configure a ARM processor for Ascending Stack growth direction?

Hello, There has been one question here which talked about stack growth direction. To which Micahel Burr had replied saying in ARM processors stack growth direction can be configured - i.e. either descending(normal behaviour) stack grows towards zero address(lower address) in memory or descending,i.e. stack grows towards higher address ...

How does x86 handle store conditional instructions?

I am trying to find out what an x86 processor does when it encounters a store conditional instruction. For instance does it stall the front end of the pipeline and wait for the ROB buffer to become empty before it stops stalling the front end and execute the SC? Basically does it force the processor to become non speculative... Thanks ...

uniprocessor or multiprocessor

lower level assembly language? (how are processor instructions implemented?)

So the lowest level we can "program" is individual instructions on a processor, but those instructions had to be programmed somehow in the first place. How does a processor know what to do when an instruction is run? ...

Is this the right way to get the grand total of processors with WMI on a multi-cpu system?

I don't have access to a multi-socketed computer, so I am unsure if the following will get the grand total of processors and logical processors. I assume ManagementObjectSearcher will return an instance for each socketed CPU and I just keep a running total? int totalCPUs = 0; int totalLogicalCPUs = 0; ManagementObjectSearcher mos = ne...
