As far as I know TRIPS was abandoned.

The problem with dataflow architectures is the interconnect when random producer must be connected to random consumer. That true for wide non-dataflow too – the crossbar that feeds belt to FU is the clock constrainer on a Mill. Yes, Tachyum can package instructions into call-like blocks – but it’s rare for the blocks to be more than a few instructions. That’s because most code references globals frequently, and those references must preserve order because the languages don’t provide reliable ordering semantics. So one can turn a whole sqrt routine into one of their blocks – but trying to make a block out of a loop body, so separate iterations can be spun out to their own core – that’s much harder. The analysis is the same you have to do for auto-vectorization, and the result is not pretty albeit it can be lovely on cherry-picked micro-benchmarks.
