Streaming Channels with L1s
How many streaming channels can you have within a single core? E.G, If I have 5 threads running on 1 500 MIPS L1, how many streams can connect between them?

You can have 32 chanends on one core, so no more than 16 streaming channels.Bianco wrote:Correct, within the same core you can have as many as you want.waluigi wrote:As many as you can have channels I think....

Can you do that in XC though? "Streaming channel" is an XC concept... :-)Ross wrote:Or 32 to themselves... ;)segher wrote:

Wouldn't be 15 max? I Though there had to be 1 left (assuming you have more than 1 L1).

In practice you will need a channel end (or a few) to do stuff, sure (also when you haverp181 wrote:Wouldn't be 15 max? I Though there had to be 1 left (assuming you have more than 1 L1).
only one core). But assuming you can actually use all channel ends, you get 16.
I carefully said "no more than 16" btw :-)
