Parallax Propeller, why is it so overlooked?

rwgast
rwgast over 10 years ago

So the parallax propeller is a 32bit 8 core micro. It is what I learned to electronics/embedded coding with! Its basically like having 8 AVR chips in one and never needing an interrupt. Currently im taking the time to learn PASM or Propeller Assembly. I curious as to why there aren't more of these out in the wild? Im also learning ARM and would one day like to switch from electrical to embedded as a career.... but I feel like I am wasting my time with this chip even though its great especially for industrial and robotics multitasking at the bear metal level. I never see a propeller chip in a job discretion or in a product. To me the prop is very close to a software defined CPLD as is maybe the XMOS.

 

What do you all think about the propeller chip?

    The Propeller chip is unpopular for so may reasons: it is very limited compared with ARM Cortex and far from cheap. The 8 processor model is difficult to design with and this puts people off but there…

    Im not sure what the issue is, but not having a compiler as well as flaunting a new , much more powerful version doesn't help. THough they have yet to release it and its been like 4 years at least! Arm…

    What does it matter?  Either one you would need to understand internals with ASM.  If you are using C the learning curve would be about the same....  Confused.

    Anytime you need to coordinate multiple processors, the troubles begin. I know this from working on big multiple CPU's at work. If totally independent, I agree no big problem.

    That's the beauty, they are totally independent!  They are called COGs not really independent processors.  Its actually easier than using PThreads IMO.  Now they have a C compiler I may be trying mine out soon, but I really fell in love with the chipkit Pi so we'll see.

    As I said I got my starts with a propeller and when I finally purchased an arduino already knowing C I wanted to do more powerful things and interrupts just seemed like an awful way to do multiple thing it throws determinism WAY off sometimes :/. I Use ARM base mcu's and AVRs alot, put I still think processing in parrallell is a much better pardaigm for small micros if exact timing is needed.
