1. An apparatus to restore an encoded image, the apparatus comprising;

  • a decoder configured to perform a restoring process on the encoded image, the decoder including;

    a memory configured to store a plurality of processor instructions;

    a processor configured to execute an intra-mode restoring function on the encoded image using the plurality of processor instructions; and

    a hard-wired circuit configured to execute an inter-mode restoring function on the encoded image, andwherein the decoder configured to perform operations comprising,determining a memory access frequency of the restoring process or a number of operations of the restoring process,identifying the restoring process from among the intra-mode restoring function and the inter-mode restoring function based on the memory access frequency of the restoring process or the number of operations of the restoring process,switching to the intra-mode restoring function in response to the determining indicating that the memory access frequency is below a first threshold or the number of operations exceeds a second threshold, or to the inter-mode restoring function otherwise, andperforming the intra-mode restoring function or the inter-mode restoring function selected by the switching, the intra-mode restoring function being performed by executing the plurality of processor instructions, the inter-mode restoring function being performed using a hard-wired circuit.
