There is the Atom subset of Haskell meant for embedding, if you are
not aware of it:
"Atom is a Haskell DSL for designing hard real-time embedded software.
At Eaton, we use it for automotive control systems. Based on guarded
atomic actions, and similar to software transactional memory, Atom
enables highly concurrent programming without the need for mutex
locking. In addition, Atom performs compile-time task scheduling and
generates code with deterministic execution time and constant memory
use, simplifying the process of timing verification and memory
consumption in hard realtime applications. Without mutex locking and
run-time task scheduling, Atom can eliminate the need and overhead of
RTOSs for many embedded applications."

I used another of Tom Hawkins' projects - Confluence - several years
ago. It was an excellent tool for FPGA design - much more efficient and
natural than writing Verilog or VHDL, and far easier to write correct
code. But he got bored with the project, and moved on - and Confluence
stagnated. Take that both as a recommendation and a warning - judging
from Confluence, Hawkins is a smart guy and produced a very imaginative
and out-of-the-box tool. But it also shows that for a project to really
live, you need more than a couple of people doing some research - you
need enough people to have a continuation of the project over time.
