#92717 - real time Responding to: ???'s previous message |
real time is two different things depending on whether you are doing something fit for a microprocessor application or something fit for a microcontroller application. For a microcontroller app real time means "immediately" for a microprocessor app it means "soon enough".
Higher up you can read: For sure, doing pre-emptive task switching with the 8051 can be limited by the 256 byte stack, but that doesn't preclude you from doing it. Of course, if youn are bending, folding and mutilating the '51 to behave as a microprocessor, using a RTOS makes sense ... but does it make sense to force a '51 into a microprocessor app? In this discussion I have seen a confluence of using the '51 as a processor (NOT a controller) and the advocay of using a '51 RTOS. Erik |
