Blackfin

The Blackfin processor was designed by and is manufactured by Analog Devices (Board and Chip Vendors). Several boards that include a Blackfin processor are available (Hardware Hacking).

All Blackfin processors include Debug/JTAG Interface for in-system debugging.

Blackfin processors are fast enough to support real-time H.264 video encoding.

The "MMU" on Blackfin processors supports memory protection for "user" programs, and is more than adequate for running uCLinux. But it apparently doesn't have the "memory mapping" feature required to run most other Embedded Linux Distributions.
