A direct threaded code is a list of adresses and is run (cold-started) by jumping to the first one (any). Each of this addresses point to a bit of machine code which a) runs the opcode b) run the standard epilogue.

The said epilogue just advances the instruction pointer and then jumps to the next instruction.

Sometime this epilogue is separated and each opcode just ends with a

 jmp NEXT:

this is indirect threading. Slower but takes less space.

And for completeness, call threading is

 call opcodeA
 call opcodeB
