Abstract
An electronic device having a scratchpad memory and a management method are provided. A recording circuit records multiple counter values which correspond to entries in a Translation Lookaside Buffer (TLB). A virtual address is matched with a first entry. If a cache miss occurs, the recording circuit updates a first counter value corresponding to the first entry, and determines if the first counter value meets a threshold criterion. If the first counter value meets the threshold criterion, the recording circuit transmits an interrupts signal to a processing unit, and the processing unit moves data into the scratchpad memory. If the first counter value does not meet the threshold criterion, the data is moved into a cache.
