memory management. VxWorks supports virtual memory while RTLinux uses a strict linear memory translation. This makes RTLinux more predictable but at the same time it lacks support of memory protection. A mistake by a programmer can bring the whole system down. RTLinux only supports static memory allocation while VxWorks supports dynamic memory

Keep the following considerations in mind when using a VxWorks target: General. The RTOS does not support virtual memory or memory protection. If one task crashes, the target restarts to avoid unpredictable effects on other tasks. Time zone changes require a target restart. File System and Directory Structure. The file system is not case-sensitive.

§ Virtual memory support etc., VxWorks provides a real-time kernel that interleaves the execution of multiple tasks employing a scheduling algorithm. Thus the user sees multiple tasks executing simultaneously. VxWorks uses a single common address space for all tasks thus avoiding virtual-to-physical memory mapping.
