Modern Intel x86-64 chips, if you squint. They read in 120-bit wide
"instructions", which consist of up to six x86 instructions which it will
attempt to execute in parallel.
The implementation is outrageously inefficient compared to a "proper" VLIW
system, not least because of the sheer amount of logic required to even figure
out where the instructions start and end, but because the instruction set is
not tightly-coupled to the architecture, it allows the design to evolve without
having to recompile the world with each new model.
