From: Rick North on 23 Feb 2006 16:04 Hi All, I have tried to get some information about RTOS from different suppliers, but I find it hard to cut trough the marketing and sales pitch persons. Before you can get any answers, you have to answer 50 questions to get any info at all and then they want to demo their excellent RTOS. Taking more of your time. So I thought I might ask the community if they have any real life experiences and 'gotchas' to share. Have anybody used the PPC405 inside a Virtex-4 with a RTOS? Which one and what grade would you give it? My application is a central control FPGA which handles some communication via RocketIO and some data recording and calculation. Hmmm.... it is a general question. Cheers, /Rick

Rick, please email me - I'm aware of at least one RTOS developed for that combination, but I don't want to post an advert. ;) pete -- pete(a)fenelon.com [Support no2id.net: working to destroy Blair's ID card fraud]

It's inexpensive yet solid, and it gets the job done. If you need real-time and you want all the Unix trimmings consider VxWorks from Wind River. It's _spendy_, and the support folks are all snobs, but it the RTOS part is solid and it does have all the trimmings. I'd use VxWorks again, but only after considering alternatives like Linux and eCos. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Posting from Google?

From: Ansatt on 24 Feb 2006 02:03 Don't use VxWorks. Over priced, over rated and with a stinking support. I know because we use them, but next time we will not give them so much as a thought.

VxWorks is not cheap by any stretch--around $7K per seat. But, the RTOS has been around forever and is qualified by many US govt agencies (NASA, DoD, et al). I'm utterly *unimpressed* by their host/build environment and the fact it sits on top of GNU tools. However, the target OS is good. I share your frustrations with the RTOS vendors. My digging convinced me that you are not going to get any commercial RTOS for less than $5K. Pretty steep for any small system... Paul |
