Although, not what your thinking of, there were several
Forth engines made.
Most of the low level words were single instructions.
In fact many low level words were often combined
as single instructions.
It still needed the string interpreter for interactive
but compiled was mostly values that translated
direct to execution.

If you consider a microcoded processor that accepts BASIC statements and
tokenizes them on input, and executes the tokenized code when the BASIC
program is run a "hardware" implementation of BASIC, then this probably
fits the criteria of the posting above.
But did not the classic computers, in the late 50's plan for the very
same idea, with true stack based languages using logic gates rather than
microcode. Getting side tracked with time sharing, is what gave us Basic
in my view. Ben.
