Any RTOS to report latencies?

Greetings, I am wondering are there RTOSes that document interrupt and task switching latencies on supported platforms and provide with tools to validate that. I read some advertising hype from OS vendors on how small their latencies are, but there were no numbers. There were also several independent studies that got to numbers, which OS salesmen probably prayed would have never been publi...

Hi all, we are on the point of taking the decision of buying Nucleus PLUS to be used in a new device (quite similar to a mobile phone and using OMAP5910). The only point against it is we don't know too many examples of Nucleus working in 'popular' devices/products and, since we have no experience in RTOS at all, our bosses doesn't trust Nucleus means against others like OSE, Integrity.

Hi, In my latest RTOS, I have timers on every service (i.e., every service invocation can return ERROR_TIMEOUT in addition to SUCCESS or FAILURE). But, the common approaches to providing timers (not just timeOUTs) don't "feel right" when applied consistently like this. I'm wondering if there is something I can exploit to "cut a corner" in my implementation... E.g., allocating a "pool"...

Greetings, When a program is too big to fit on a microcontoller internal memroy, external memory has to be used. Thats when a bootloader is needed. Does a bootloader go hand in hand with an RTOS or is it sometimes used to without one? Also, what kind of memory is typically used in this setting, and how is it updated? Thank you for your input. -- a

I am trying hard to avoid embedded stuff these days, but potential contract has come my way recently that needs some embeeded stuff. So whilst I am nutting out requirements I also need to put thought to software. I have made the descision that the software must be based on an OS and must have a c++ compiler. RTOS is not required. So the debate in my brain has been fired off. My first thoug...

I.e., the application has the tools it needs to optimize its power consumption *if* it knows what that is! ...
