One interesting feature is that it has two real-time co-processors (programmable realtime units or PRU's) that might be good Forth targets. They are 32-bit non-pipelined RISC cores with 8k program memory and 8k data memory, plus 12k of shared memory (I guess shared between the two PRU's). They are intended for uses like motor control. It's interesting that the PRU's don't seem to support signed arithmetic-they only have unsigned addition and subtraction. They don't have multiplication either, i.e. they're not DSP's.
