A data accessing method executed by a processing unit, the method comprising the steps of: (a) decoding an instruction; (b) checking whether the instruction has to be repeated M times to read data with successive addresses in a main memory, wherein the number M is stored in a count register of the processing unit; (c) if the step (b) is true, getting a data from a cache, a pre-fetch buffer, or the main memory, and then decreasing M by one; (d) if M is zero, terminating the data accessing method; (e) determining and pre-fetching data by comparing M to the number of unread data stored in the cache and the pre-fetch buffer; and (f) getting the next data from the cache or the pre-fetch buffer, decreasing M by one, and then returning to step (d).
