'AMRISC' SoCs

 * Many older devices manufactured by Advanced Multimedia Internet Technology (AMIT)
 * (an OEM/ODM of products used by numerous brands) use 'AMRISC' marked SoCs.


 * Many (if not all) of these appear to be designed / manufactured by RDC and AMIT
 * is the only known manufacturer to use them within their products.
 * The font used on the chip looks to be the same as additional SoCs
 * more tersely identified w/ relation to AMIT (AMITSOC).

They may be quite similar (if not identical to) some existing RDC products.

Note: 'AMRISC' was previously used by Amlogic with reference to their products, but it doesn't seem have been trademarked by them (currently, it's trademarked by a completely unrelated company), and does not have any reference of these chips. Amlogic offered MPEG video decoder chipsets and other multimedia products at the time and never indicated they were targeting the home networking market.
 * Their products have also used AMLxxxx part numbers throughout their existence (up to now), which is not consistent with these SoCs.
 * Some other sites state that Amlogic is indeed the manufacturer, but it is almost certainly in error.
