The Aeolia is a secondary processor acting as a sort of southbridge for the PS4. It is an ARM-based SoC produced by Marvell that handles several tasks to offload the main processor/[[APU]]: | |||
* Network connections ([[Wireless]] and [[GbLAN]], including background downloading -> [[PlayGo]] | |||
* File handling ([[Bluray Drive]], [[Harddrive]] and [[USB 3.0]]), including background caching | |||
* Main serial flash handling | |||
It is connected to its own DDR3 worker RAM ("sbram") [[K4B2G1646E-BCK0]], the main serial flash [[MX25L25635FMI-10G]], SATA bridge [[MB86C311B]] and [[GbLAN]] controller [[88EC060-NN82]] etc. see also [[:File:PS4_-_SAA-001_diagram.png]] | |||

''This secondary processor was initially nicknamed '''MediaCon''' by the community before any official release because of its role of handling media (online [[Wireless]]/[[GbLAN]], [[Bluray Drive]] and [[Harddrive]]) even in standby. Its official name is Aeolia, as mentioned in Orbis kernel logs.'' | |||
The Aeolia is connected to the [[APU]] by [http://en.wikipedia.org/wiki/PCI_Express#Pinout PCI_Express x4]. It runs its own FreeBSD system in standby mode, presumably activated to handle tasks such as downloading updates while the PS4 is in standby. | |||
