SoC (system on chip) selection

[Nico Coesel]

Hello all,
For an upcoming project I'm working on assembling a long list with
system on chip devices which may suit the project.

I've already came across the Alchemy devices (formerly AMD now RMI),
Freescale and the Blackfin from AD. But I'm quite sure there are other
alternatives around....

Rough specs:
- 500MHz or more
- DDR memory interface
- LCD panel controller
- USB host
- SD card interface
- AC97 interface
- 2 UARTS
- Capable of running Linux preferably with MMU
- On chip ethernet MAC (or an easy way to connect an external ethernet
controller)
- A camera interface would be nice
- Supported by GCC

price: cheap. Say aroud $10 in larger quantities.

Offhand and _NOT_ being an expert, i would suggest a 2 chip solution.
Chip one a CP including MMU and the fast interfaces (including
ddr/ddr2 memory, p/o 100/1000 Ethernet (exclude the MAC) and PCI.
Separate LCD controller from integrated standard XGA.
Second chip AC97, UARTS, Firewire, Fast USB, and fast SD, PCI
interface to fast chip.

That is very much like the AMD Geode architecture (VIA also offers
these kind of solutions) but these are not very low cost. More likely
to be around $25 to $30 and very power hungry.
