1. A command accessing method having a power saving mechanism, comprising:
controlling a cache control circuit to retrieve a plurality of commands;
determining a plurality of loop commands that correspond to a loop procedure comprised in the commands, wherein the loop commands comprise a first part having a size that matches a storage amount of a command buffer circuit and a second part that exceeds the storage amount of the command buffer circuit;
controlling the cache control circuit to store the first part of the loop commands to the command buffer circuit and not store the second part of the loop commands to the command buffer circuit; and
every time the loop procedure is performed, controlling the cache control circuit to retrieve and execute the first part of the loop commands from the command buffer circuit and retrieve and execute the second part of the loop commands.
