rtos - Basics of Real Time OS -


i trying learn rtos scratch , this, use freertos.org reference. find out site best resource learn rtos. however, have doubts , trying find out not able exact answers.

1) how find out device have real-time capability e.g. controller has (ti hercules) , other don't have(msp430)?

2) depend upon architecture of core (arm cortex-r cpu in ti hercules tms570)?

i know these questions make nuisance, don't know how answer of these questions.

thanks in advance

edit:

one more query have meant "os" in rtos? mean same os others or it's contains source code file api's?

figuring out whether device has "real-time" capability arbitrary , depends on project's timing requirements. if have timing requirements high, you'll want use faster microcontroller/processor.

using rtos (e.g. freertos, ecos, or ucos-x) can ensure given task execute @ predictable time. freertos website provides discussion of operating systems , means operating system claim real-time capabilities. http://www.freertos.org/about-rtos.html

you can see ports pages of uc/os-x , freertos can run on variety target microcontrollers / microprocessors.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
