I haven't seen any standard video processing (x264/NTSC/MPEG) on current Cortex-M3 board yet. And I just bought a STM3210E board few days ago XD

Here is an interesting website. In particular, post #16.

Hi,

 Is there any preliminary preliminary documentation publictly available, or still being a secret?

(As the new devices are already in preliminary sampling stage)

The current consumption is close to that of Energy Micro EFM32 (180uA/MHz)

sampling now.

BTW, interesting comparison here

Hi,

 Any update on the new device, yet?

Hi,

 No EEPROM (you can emulate it), but other things are already on current STM32s. You can do DMA transfer to/from GPIO - see appnote for timer triggered DMA. You can use FSMC to interface to FPGA, LCD, etc.

Do any have EEPROM?  Even 64 bytes would be a BIG help.

I would also like to see some kind of GPIO with DMA.  At least 8 data bits (an option for 16 or possibly 12 data bits would be nice.)  Will need h/w protocol lines.  CPU i/f can assume connected device knows if it is reading or writing.
