Triple mode redundancy can be implemented in a Xilinx Zynq System on Chip by using the built-in redundancy features of Zynq's programmable logic (PL) and processing system (PS) components. This can be achieved by configuring the PL to implement triple modular redundancy (TMR) for critical logic and using the PS's built-in redundancy features to implement TMR for the processor and memory subsystems.
In the PL, use the Xilinx TMR IP core to implement TMR for critical logic. This can be done by instantiating the TMR IP core in the PL and configuring it to triple duplicate the critical logic.
In the PS, use the built-in redundancy features to implement TMR for the processor and memory subsystems. This can be done by configuring the PS to use triple-modular redundancy for the processor and memory, and by setting up the PS's built-in error detection and correction mechanisms to detect and correct any errors that may occur.
At the software level, you can use a voting algorithm to compare the outputs of the three replicas to determine the correct output.
Please note that the above steps provide a high-level overview of how to implement TMR in a Xilinx Zynq, and specific implementation details will depend on your particular application.
