Abstract
A device and a method for fetching instructions. The device includes a processor adapted to execute instructions; a high level memory unit adapted to store instructions; a direct memory access (DMA) controller that is controlled by the processor; an instruction cache that includes a first input port and a second input port; wherein the instruction cache is adapted to provide instructions to the processor in response to read requests that are generated by the processor and received via the first input port; wherein the instruction cache is further adapted to fetch instructions from a high level memory unit in response to read requests, generated by the DMA controller and received via the second input port.
