For example, consider an 8051 microcontroller application with no external memory. In this type of environment there is simply not enough RAM memory to accommodate a preemptive multi-tasking kernel
Translated: To do this we need to use an artificial stack in XDATA, fortunately they will buy our RTOS before they realize how much processing time that takes. Erik That's a bit naughty Erik. The rest of the quote is: The cyclical executive is small, compact, and easy to use and understand. On the negative side, there are no priorities, busy waiting is employed, and more responsibility (e.g. timer management) is put on the programmer. Translated: So there's no point us trying to sell you a full blown RTOS for a basic 8051 because we just told you it's a waste of time and Erik's workloop will do you for many applications. Not only that, our RTOS is free anyway. Ian |
