LMM code in PROPBASIC

denno

Bean....I have an experiment going on using the FLIP, and PROPBASIC. I have written code to all 8 cogs, using the command TASK. Now, if I put LMM after the TASK name, on all 7 COGs after the PROGRAM start, the first COG (0) will start, but the rest of the COGs do not run. I still get a successful download to the FLIP. Now, if I remove the "LMM" from the last COG(7), but leave the rest of the COGs with the LMM in place, the download works and all COGs are running.

If I remove all "LMM"s the program still loads, and runs correctly... so, what does the "LMM" do?

LMM allows you to make larger (much larger) program for a single cog. However, they only run about 25% as fast.

Usually the main program is LMM and all of the tasks are native (not LMM).

Not sure why you wouldn't be able to run 7 task that use LMM (that is not the norm, but should work).

Thank you Bean...I will keep playing around with it....and again thank you. What does LMM stand for, anyways?
