Hi, Can anybody suggest me good rtos material.I have good amount of exp in embedded software devp.I've never used any rtos so far.Something tht will help me leverage my exp would be great Thank u Vishal Patil
Yeah he's right. uC-OS is the cheapest way for an individual to get his feet wet in RTOSes.
As far as priorities, multithreading, multitasking, interprocess communication, etc. goes, RTOS concepts are closely familiar with Unix-like OSes (e.g. Minix, Linux). You can install these on a PC and play with the mechanisms mentioned in the previous sentence.
In fact, from a programming point of view, the determinism that makes an RTOS an RTOS is usually transparent to the programmer for the most part, even to a device driver developer. (I might be wrong though, because i haven't touched an RTOS since 2002). Thus, it is more important to know OS concepts, which are applicable to 99% of your programming in an RTOS.
For a good description of multi-threaded programming concepts used in most RTOSes, try "Multi-C" from MiX software. It is written in a tutorial style and includes full C Source for a Multi-threaded library based on coroutines. (Cooperative multi tasking).
(Tracing through an example program using a source level debugger is quite interesting)
Sheesh, I didn't know that Dr. Comer had yet another Xinu book out.
But I completely agree that Doug's books are probably the very best way to learn about operating systems, if you are new to the subject. Most operating system books presume a teacher is there to help out or just dive in and cover all of a range of broad subjects. Even Tanenbaum's books, which get into some practical details, are overburdened by the details of fabricating a fairly sophisticated O/S. In contract, Comer comes at things in surprisingly simple fashion and yet with very useful results for many. And it speaks well, I think, to those trying this for the first time.
I don't think he does. There's no "mount xinu" book as far as I can tell. The original Xinu book came out twenty years ago, and (IIRC) about fifteen years ago it was revised and split into two volumes. It's been out of print for a long, long time, but you can still get paperback on-demand laser-printed "facsimile" versions for $90.
