Which could be more effective for an embedded?Real Time System to meet the asynchronous signal timelines ???
A fast processor with RTOS or a muti processor approach ?
For example, a system has 4 inputs, (a) a Gyro (b) x-y-z accelerometer (c) user keypad (d) GPS data...
which is a better approach...couple all the inputs to
(a) a fast processor?running an RTOS like VX works or micriumIII
(b) or else use 4 independent processors, say a 32 bit one running at 80 MHz that processes the input and transfers?the processed data over a serial protocol to a fast processor that takes the corrective action ???
Which one would you propose since the above Real Time System is a Safety Critical system..e.g. a Flight Controller.
