Abstract

Method and apparatus for initializing a system configured in a programmable logic device (PLD) is described. In some examples, the method includes: initializing memory elements in the system with first data; executing a first iteration of the system to process the first data; partially reconfiguring the PLD, during execution of the first iteration, to initialize shadow memory elements in the PLD with second data, the shadow memory elements respectively shadowing the memory elements in the system; transferring the second data from the shadow memory elements to the memory elements; and executing a second iteration of the system to process the second data.
