Extending 4-Bit Burst Error-Correction Codes with Convolutional Interleaving

The reliability of electronic systems lies in the fact that it can store and retrieve accurate data. Since the data storing elements, memories perform an essential role in space application. The space radiation cause error in the data saved in the memory. As technology advances and cell interval distance decrease, the memory cell area is getting reduced, and more cells get affected by this space radiation. Existing error-correcting codes can use for correcting up to 4-bit burst errors. I propose a technique that extends quadruple adjacent error correction codes with convolutional interleaving to improve reliability. The interleaving and deinterleaving procedure of the proposed method is illustrated with an example. The encoders, decoders, interleaver and deinterleaver implemented using VHDL in Xilinx ISE Design Suit 14.7. The simulation result shows that a burst error that affects more than four adjacent bits can be corrected using the proposed method.
