AT91CAP9S500A (ARM9 + FPGA-port)

Why FPGA?:

Take a look at this microcontroller, that integrates an ARM9 microcontroller and a dedicated FPGA port: AT91CAP9S500A. It has "only" a max. clock at 200MHz, but can use a FPGA for hardware acceleration, that could be used for video (de)compression, aacPlus v2/HE-AAC v2 sound (de)compression and many other things. HE-AAC v2 is better than MP3.

This seems to be a good hardware mix (ARM+FPGA). It does Ogg Theora or MJPEG in the FPGA with 1 million gates:

Just another FPGA+microcontroller example:

I do not think this means what you think it means... I read "...and a metal programmable (MP) block of 500K gates of digital logic." as meaning that it's a one-time programmable block, more akin to a standard-cell ASIC than an FPGA. This is supported by the fact that their development board contains a separate FPGA chip. Now, granted, having a 500K gate ASIC on board an ARM is a cool thing... but not quite as cool as this chip appeared at first glance.
