Apparatuses and methods for instruction scheduling in an out-of-order decoupled access-execute processor are disclosed. The instructions for the decoupled access-execute processor comprises access instructions and execute instructions, where access instructions comprise load instructions and instructions which provide operand values to load instructions. Schedule patterns of groups of linked execute instructions are monitored, where the execute instructions in a group of linked execute instructions are linked by data dependencies. On the basis of an identified repeating schedule pattern configurable execution circuitry adopts a configuration to perform the operations defined by the group of linked execute instructions of the repeating schedule pattern.
