A scaling device for receiving and scaling a digital image signal includes a scaling module and a data quantity control logic. The scaling module scales the digital image signal and then outputs a scaled output signal according to a scaling ratio. The data quantity control logic controls output quantity of the scaled output signal according to a scaling ratio. Thus, when the data quantity outputted from the scaling module is controlled within the data quantity that may be processed by the post stage of the scaling module per unit time, the data quantities that may be processed per unit time in the post stage processing devices of the scaling module approximate a constant value such that the post stage processing speed of the scaling module may be increased.

An error correction device includes a main memory, a memory bus coupled to the main memory, and a correction module. The correction module is coupled to the system bus and directly connected to the memory bus. The correction module reads an error data from the main memory via the memory bus according to an error address, generates a correct data according to the error data and an error value, and directly writes the correct data into the main memory via the memory bus. Because the correction module reads and writes the correct data into the main memory without using the system bus managed by an arbitrator, a number of the change row operations can be reduced to increase system efficiency.

Error correction apparatus and method for data stored in memory

An error correction device includes a decoding unit, an error buffer, an error classifying unit and an error correction unit. The decoding unit reads data from a main memory and performs error detection on the data to generate error values and error addresses. Then, the error buffer temporarily stores the error values and the error addresses. The error classifying unit classifies the error addresses stored in the error buffer into a plurality of subclasses, where error values and error addresses which correspond to the same row of the main memory are classified into the same subclass. Finally, the error correction unit performs an error correction on the data stored in the main memory according to the plurality of subclasses. The error correction device therefore can reduce the amount of the change-row operations of the main memory so that the memory efficiency is increased.
