Abstract
A system and method for finding available memory space associated with an inactive memory transfer controller and activating the inactive memory transfer controller using indexed addressing. A memory transfer engine includes a plurality of memory transfer controllers, each configured to move data from a source address to a destination address. An active memory transfer controller can execute an instruction to find an inactive memory transfer controller associated with available memory space. The inactive memory transfer controller is activated by writing to its hardware registers, thereby assigning it a task, using indexed addressing.
