  1. Re: The New 16-Cog, 512KB, 64 analog I/O Propeller Chip

    Chip

    Looks good...hubexec at 50% should be just fine...it will give people incentive to think creatively in using cog memory for faster code:) Plus the option of using hubexec.

    Re: Putting smarts into the I/O pins

    I don't fully understand how the 'smart' pins will work...but I am guessing??? that they can/could be used to bring back color modulation and one line composite video?
  3. Re: The New 16-Cog, 512KB, 64 analog I/O Propeller Chip

    Would it be possible to set the number of cogs that can access the hub memory...therefore increasing the bandwidth to hub memory...

    etc have a setting so all 16 cogs access memory..one to set it...

    Chip

    Looks great...I might need to buy a DE0-Nano to do some testing:)

    I would not worry about the code compatibility (with the P1) or the loss of the composite color modulation...Composite...

    I could not agree more...great post...

    Chip if you could solve/include a hub exec routine in the 16 cog p1 plus model...that feature might be the best of both worlds

    Re: We're looking at 5 Watts in a BGA!

    I vote for the p1b...it sounds awesome...512 ram...more cogs...short turn around time.

    I like the new ideas....512 RAM rocks...it satisfies my needs more pins, more speed, more memory, and more cogs...BUILD IT:)

    Plus less items to test out...

    I like option A...as long as Parallax makes small affordable break-out boards. The package design doesn't matter...Board design is something that does not interest me. Since the prop 2 will not...

    Re: Hub Execution Makes Things Too Open-Ended

    It looks like your lack of sleep is starting to show. Hubexec is an awesome feature for the prop2. It will open BIG doors...I realize it could cause some laziness in coding, but in the...
