Abstract:

For high consequence applications requiring information assurance, the architecture of the Xilinx Zynq-7000 All Programmable SoC precludes a tightly-coupled lockstep approach between the two processors. Therefore, a loosely-coupled lockstep approach implemented by a transaction checker residing in the Programmable Logic portion of the Zynq device will be discussed along with implementation results and latency measurements.
