[Arm-netbook] Any ARM SoC has Open-Source access to hardware video decoder ?

[Jacky Lau]

With the power of open source community, you can run a fabless company
by one million U.S. dollars per year.
For cost down, you can employ mips cpu core, vivante gpu, ceva vpu,
and I/O controllers from opencores.org.

If you want more open, you can employ openrisc1200 cpu core[1], ORSoC
gpu[2]. They're full open sourced.
Maybe you can find some useful video codec ip core from opencores.org
too. All you need to do is integration,
verification and writing drivers.

I do not know how the performance of the ORSoC GPU is, but the
performance of or1200 is arm9 class. If you
want a a9 class cpu core, beyond semiconductor provide Beyond BA14 cpu
core[3]. But it's not open sourced.
It's reasonable, because a good micro architecture need many people,
time and $ to design and implement.

There is another option, license a MVP cpu core from ICube tech[4].
The MVP cpu core is designed for do cpu,
gpu, vpu job in single core. After license the MVP cpu core, all you
need to do is integrate the I/O controllers
and write code. Soc developer is more different to find than software
developer and Soc development need many
people, time, & $. If one core can do three cores' job, the power
consumption and cost will be lower. And you
can do more innovation on the programmable cpu core. They had told me
that their customer will ship a product
this month. Maybe you can contact them for more information.
