rtos for 8051

I have to make an rtos for 8051.

1.what are the functions performed by bootloader during startup of the chip?
if i can execute a program on my chip stored at any location in memory then what do i mean by making a separate OS for 8051?

please help me..

regards,
M.Stephen Selvaraj

  • How much more than 1.5GHz?

    1.5GHz only informs us what the clock cycle time is. It still doesn't say anything about now many clock cycles a single instruction takes, or how many clock cycles that are needed to detect that a task switch is needed and then manage to perform that switch.

    Do you detect and switch in 150 clock cycles? And normally, the real-time requirement is that the task must have responded within the stipulated time, so the task may need a couple of clock cycles too...
