1. A method of scheduling executable transactions in a multicore processor comprising a plurality of processor elements, wherein at least one processor element comprises reconfigurable logic, the method comprising: providing a first configuration queue of executable transactions corresponding to a first configuration of the reconfigurable logic and a second configuration queue of executable transactions corresponding to a second configuration of the reconfigurable logic, the reconfigurable logic comprising one of a field programmable gate array (FPGA) or a memory, the executable transactions allocated to and ready for execution by the reconfigurable logic; providing a plurality of executable transaction schedulers, each executable transaction scheduler comprising a scheduling algorithm for determining a most eligible executable transaction for execution from a number of candidate executable transactions; linking the executable transaction schedulers together into a multilevel scheduler; outputting the most eligible executable transaction from the multilevel scheduler to one of the first configuration queue and the second configuration queue; outputting the executable transactions of the first configuration queue to the reconfigurable processor element for execution when the reconfigurable logic is configured according to the first configuration; reconfiguring the reconfigurable logic according to a second configuration when a pre-determined threshold is reached; and outputting the executable transactions of the second configuration queue to the configurable processor element for execution when the reconfigurable logic is configured according to the second configuration.
