Ah, that's what we call the "CPU" now :) (Used to be "MCU", but since
we also have a PMU and now an MPU, that's too close for comfort.
We're basically constrained by what chips we can get. We decided to go
with Samsung again, since we perceive this to have the lowest design
risk for us. GTA04 will have a Samsung 6400. Clock rate will be roughly
the same as in GTA02, but the ARM core is more modern (ARM11 instead of
ARM9), which brings a number improvements.
The 10 page technical brief -
http://www.samsung.com/global/business/semiconductor/productInfo.do?fmly_id=229&partnum=S3C6400
does indeed make it look shiny.
I note that the 6410 has 3d accel, and claims to be a straight drop-in,
which is nice. (I haven't got access to the datasheet yet - if they'll
let me.) And references to a drop-in 6430 - but no details.
Is there a GTA03?
500MHz, with DDR RAM (possibly), and onboard 2d accel should really fly
- even for screens as 'large' as VGA.
