ERROR CORRECTION DEVICE AND ERROR CORRECTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18511740 titled 'ERROR CORRECTION DEVICE AND ERROR CORRECTION METHOD
Simplified Explanation
The device described in the patent application is designed to receive Error Correction Code (ECC) codewords from an external device, correct errors in the received data, and generate cyclic redundancy check (CRC) codewords to check for errors in the corrected data.
- Receiver to receive ECC codewords transmitted from an external device through a channel
- ECC decoder to correct errors in the ECC codewords and generate a CRC codeword based on the corrected data
- CRC checker to determine if errors exist in the CRC codeword
- Post ECC decoder to generate a second CRC codeword if errors are found, based on error correction result information
- Potential Applications:**
- Data storage systems - Communication systems - Information security systems
- Problems Solved:**
- Error correction in data transmission - Ensuring data integrity - Enhancing reliability of communication systems
- Benefits:**
- Improved data accuracy - Enhanced error correction capabilities - Increased reliability of data transmission
- Potential Commercial Applications:**
- Telecommunication companies - Data storage companies - Information technology firms
- Possible Prior Art:**
One possible prior art for this technology could be existing ECC and CRC error correction methods used in data storage and communication systems.
- Unanswered Questions:**
- 1. How does the device handle multiple errors in the received data during the error correction process?**
- The patent abstract does not specify how the device deals with multiple errors in the data and whether there are limitations to the error correction capabilities.
- 2. What is the processing time required for the device to correct errors and generate CRC codewords?**
- The abstract does not provide information on the speed or efficiency of the error correction process, which could be crucial for real-time applications.
Original Abstract Submitted
A device includes a receiver configured to receive a plurality of Error Correction Code (ECC) codewords transmitted from an external device through a channel including one or more lanes; an ECC decoder configured to generate a plurality of post ECC codewords by performing error correction with respect to the plurality of ECC codewords and generating a first cyclic redundancy check (CRC) codeword based on the plurality of post ECC codewords; a CRC checker configured to determine whether an error exists in the first CRC codeword; and a post ECC decoder configured to, when it is determined that the error exists in the first CRC codeword, generate a second CRC codeword by estimating a remaining error position based on error correction result information received from the ECC decoder and performing remaining error correction with respect to the plurality of post ECC codewords based on the remaining error position.
