| Abstract: | Disucusses integrated anti-disturbance measures from the perspective of software and hardware by using the example of DSP chip TMS320LF2407A, so that reliability and security of DSP system will be improved. Hardware anti-disturbance consists of power supply system anti-disturbance, input passage anti-disturbance and so on. Software anti-disturbance is made up of watchdog technology, software snare technology and so forth. |
