Just to added everything I read about the PS4 addicinal chip (ARM)... Sony just free up the CPU, GPU and memory to be used only the game itself.
- "Encoder and video decoder hardware-based is on the tip of a separate. Therefore, resources needed for the game I do not use any and all bandwidth and CPU as well. Memories never (to capture the video play) using any" and SCEA explains.
Encoding video of game play will not be performed in the APU. I can look at all the work, and takes place in a completely different chip.
- Then, this shows that there is a possibility that the screen output from the APU is output to the display via the secondary tip once. That is, in the PS4, display output interface instead APU, may have been mounted on the secondary chip. I put out via the secondary chip screen output, you will also be easy to encode the screen buffer inside the secondary chip. If you were thinking of course, but can also be sent to the secondary chip on a separate line with output from the APU, and the output from the secondary chip I'm more natural.
- If we take such a configuration, even the secondary chip, a certain amount or more of memory and a microcontroller or processor cores is required. I put the CPU cores along the reverse, can be performed only by a secondary chip various things you will be easier. Although costs piling up into chips and external memory, because it is difficult to limit the foundry also in eDRAM, hard to guess what's going on.
