I'm not clear on your use of Ting as an instruction set reference.  What 
reference are you citing exactly?  My understanding is that this CPU 
design was originally by Ting, but maybe I got that wrong.

I assume you are referring to Koopman's book, "Stack Computers the new 
wave"?

I don't see a "minimum" set of instructions in Koopman's book.  He lists 
a lengthy glossary of Forth words which are not the same as CPU 
instructions and an instruction frequency list of Forth words which does 
not have the OR word listed with even a 2% frequency in any cases.

There is no reason why you are limited to any given instruction size in 
an FPGA.  In fact, I believe the Brevia uses an FPGA with memory that is 
a multiple of 9 bits wide.  So a 16 bit instruction word leaves 2 memory 
bits unused.  Unfortunately the iCE40 line of FPGAs only have 8 bit wide 
block memory.  If I could count on having that 9th bit in all FPGAs I 
would hard code it in myself.

One tip that many CPU designs ignore, if you look at the complexity of 
the decoding circuit, instructions that use multiple clock cycles 
increase greatly that complexity.  A 5 or 6 bit instruction with no 
timing data is very easy to decode.  Add multiple clock cycles and you 
add counter bits that increase greatly the decoding logic.  This both 
consumes resources and adds timing delays.  So a CPU design that is 
totally single clock cycle is highly desirable.  That has been one of 
the more difficult goals to meet in my designs because it impacts many 
things such as the handling of interrupts and memory access.
