multithreaded
Sharing a single CPU between multiple tasks (or
"threads") in a way designed to minimise the time required to
switch threads. This is accomplished by sharing as much as
possible of the program execution environment between the
different threads so that very little state needs to be saved
and restored when changing thread.
Multithreading differs from multitasking in that threads
share more of their environment with each other than do tasks
under multitasking. Threads may be distinguished only by the
value of their program counters and stack pointers while
sharing a single address space and set of {global
variables}. There is thus very little protection of one
thread from another, in contrast to multitasking.
Multithreading can thus be used for very {fine-grain
multitasking}, at the level of a few instructions, and so can hide
latency by keeping the processor busy after one thread issues a
long-latency instruction on which subsequent instructions in that
thread depend.
A light-weight process is somewhere between a thread and a
full process.
TL0 is an example of a threaded machine language.
Dataflow computation (E.g. Id and SISAL) is an extreme
form of multithreading.

threaded code
(foldoc) | threaded code
A technique for implementing virtual machine
interpreters, introduced by J.R. Bell in 1973, where each
op-code in the virtual machine instruction set is the
address of some (lower level) code to perform the required
operation. This kind of virtual machine can be implemented
efficiently in machine code on most processors by simply
performing an indirect jump to the address which is the next
instruction.
Many Forth implementations use threaded code and nowadays
some use the term "threading" for almost any technique used to
implement Forth's virtual machine.
