3.12 Running a BASIC Program by Multitask Processing

Here, the method of running a QD51 (-R24) BASIC program, etc. is explained.

3.12.1 Multitask processing

The QD51 (-R24) us a unit which operates by BASIC programs created by the user.

The QD51 (-R24) has one main CPU (central processing unit).
Multitasking accomplishes parallel operations by successively switching the execution
between multiple BASIC programs (up to 2 tasks).

Shows the order of
main CPU processing.

[Processing in the case of two tasks]

Example

Task 1

Task 2

In QD51 (-R24) multitask processing, switching of BASIC program execution is done
when the conditions shown below occur.

• When "Task schedule time (50 ms)" has passed.
• When a data input/output (data send/receive) command is run with respect to a

screen, keyboard, disk, peripheral device or external device.

• When a command is run which carries out control of (interrupts, stops, ends) BASIC

program execution.

• When a command is run which carries out multitask control (synchronizes execution,

starts or changes the priority, etc.).

• When a program execution interrupt state is canceled (input/output is completed, the

specified time has passed, etc.)

REMARK

Refer to the Programming Manual (Commands) concerning details of multitask
processing and commands which switch the execution of programs.
