Submitted by: Administrator

Actually theres not much of difference between using psos or vxworks.A few differences in features are:
1.The psos priority is reverse of vxworks.
2.psos supports posix 1003.1 while vxworks it is 1003.1b.
3.In psos device driver architecture is different than vxworks.
4.Also vxworks has interrupt
latency<4.33 microsecs while psos its higher.
Other then these both work in same manner and follow same
architecture.
Also as psos is getting killed no fresh development work is supported by windriver for psos. Also vxworks development environment is much more user friendly then psosenvironment becos vxworks IDE mimics mostly visual studio.
