I'd be interested in how folks see the DARPA CORE ISA (i.e. essentially
a Stanford MIPS assembly language standard as intermediate code with
optimizing assemblers underneath) as just another version of the UNCOL
ambitions.

[I was under the impression that the core isa was targeted at a relatively
narrow class of target machines, which makes the problem a lot easier. Someone
better informed than me could probably clarify this. -John]

Someone >better informed than me could probably clarify this. -John] CORE ISA (which has some very non-RISCy instruction like FPSQRT in it, and 64-bit 2-register instructions) is NOT another UNCOL attempt. It was targeted to be the target for a (small) number of stanford MIPS-like RISC CPUs. The CPUs were designed specifically to run CORE efficiently after translation (before assembly). The purpose of this is to create a family of processors from GaAs to CMOS that use the same compilers, and thus save money for the government, and make it somewhat easier to develop and test software on CMOS chips meant for blazingly fast and expensive GaAs systems. You can even write in assembler (CORE) and not have to rewrite it for the GaAs chips.
