VxWorks Task - Spawn task function as separate VxWorks thread

Library

Embedded Coder/ Embedded Targets/ Operating Systems/ VxWorks

Description

Use this block to create a task function that spawns as a separate VxWorks thread. The task function runs the code of the downstream function-call subsystem.For example:

The VxWorks Task block uses a First In, First Out (FIFO) scheduling algorithm, which executes real-time processes without time slicing. With FIFO scheduling, a higher-priority process preempts a lower-priority process. While the higher-priority process runs, the lower-priority process remains at the top of the list for its priority. When the scheduler blocks all higher-priority processes, the lower-priority process resumes.

For example, in the following image, task2 preempts task1. Then, task3 preempts task2. When task3 completes, task2 resumes. When task2 completes, task1 resumes.

Dialog

Task name

Assign a name to this task. You can enter up to 32 letters and numbers. Do not use standard C reserved characters, such as the / and : characters.

Thread priority (0 to 255)

Set the priority for the thread, from 0 to 255 (low-to-high). Higher-priority tasks can preempt lower-priority tasks.
