Make use of the TDS2020F's
power by making it do the job of many dedicated computers.
Three forms of multitasking are available on TDS2020F embedded
computer:
l Interrupt
Multitasking where an interrupt swaps the Forth system
for a new one at regular intervals. Each time it runs one pass
through a high-level Forth word and then returns, so forming
a background loop. This is a standard feature of TDS2020F in
the Forth ROM.
l Co-operative
Multitasking is the traditional Forth 'Round Robin'
multitasker where one task takes control until the word PAUSE is met which causes a
task switch to the next in the ring. This word is already placed
in input/output and delay causing routines.
l Pre-emptive
Multitasking is like Co-operative Multitasking in that
it allows I/O and delays to cause a task switch, but no task
can hog the processor for more than 10ms (default value). After
this time the task is forced to give up control to the next
one.
To receive the multitasking files you must join the Update Service
