General talk about software patterns

["Isaacs, David" <d-isaacs AT ti.com>]

I am curious if anyone has experience with the following book by 
Bruce Douglass:
"Real-Time Design Patterns: Robust Scalable Architecture for Real-Time 
Systems"

At one point, I intended to read the book as soon as it was available but then
I left for a non-real-time project and have not ventured back into that
world...

Any opinions on that book?

Hi Christophe,

Thanks for yours and everyone else's replies, they have been very helpful and 
encouraging.

Interestingly enough, I have been tossing around what you have stated in your 
first answer - this seems to really be an under-represented subject; it would 
really be useful to a lot of people to understand how to apply design 
patterns to embedded systems. 
Especially since (in my opinion and experience) a lot of people designing and 
writing software for real-time systems come from an electrical engineering 
background (like me) and were not heavily trained in computer science 
concepts.  They also tend to be more classically trained (read: structural 
software) and do not have a strong background in OOP.

I'll take a look at the book you mentioned.

Thanks a lot!

André Benassi
