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...
