| RenCutypoison said: The dedicated hardware part must be a part of the APU with a bridge connecting the GPU so that every Image send trough video out is send to RAM, then every pack of X images are sent back to the GPU (A part of the GPU dediacted to video encoding) and thus the 15 minutes limit is the RAM limit. That's how I would do it tough, it may not be that way and I probably say shit. |
That would be the dumbest way to do it as it greatly bogs down your main memory bus. I'd simply use a "listening chip". This "listening chip" (we axtually know there is something in the apu doing something with video streams) hooks into the digital stream to the hdmi video out, compresses the stream on-the-fly, and sends the compressed stream to the harddisk/to the internet connector. This way, not a single main memory cycle is used. While 176GB/s sound like a lot, you do not want to waste any byte of that bandwidth to secondary tasks. better throw in some more $ even if the beancounters protest...
In fact, if it is not done (somehow) like this, M. Cerny/whoever designed the system would lose a lot of respect from me.
