Cool. Yeah I've done a lot of contemplation on this specific situation as well as other PRU related things, and this to me just makes sense. After having seen you write that certain PRU operation can slow things down considerably. And going out over the L4 interconnect to DDR memory . . . seems like it'd be much slower. But you know, you have the hands on, I do not. Sooner or later perhaps I can, and will justify the time to start toying with the PRUs on a regular basis. But I've not needed anything "fast" yet. I'd probably use the PRUs for a different purpose than what I image you're using them for though Charles. One idea I've had lately is to use two Serial modules as an IPC mechanism between a supervisor type service running as root, and a regular user Serial side. But If I implemented the Serial ports in software by way of the PRUs, it could be really fast. Granted I'm having a hard time thinking of anything that would require that speed( that I'd personally need ). -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
