Hamming Codes on SRAM Based FPGA for Space Applications

-This paper discuss about the method for designing error tolerant systems in SRAM-based FPGAs. SRAM-based FPGAs are preferred in mission based critical space applications. But due to high radiation on the sensitive part of the circuits which introduces errors called Single Event Upset (SEU).Sometimes these types of errors results the permanent malfunction of the entire system. Different error detection techniques were used, of these highly preferred is Triple Modular Redundancy (TMR). Here proposes an error detection and correction method to protect the memories against the soft errors. The method is based on Hamming Codes in which parity bits are inserted on the data to be transmitted. Encoding and decoding of data which increases the security. This technique which provides multi bit error correction together with adjacent error detection. This is a promising technique with faster reconfiguration and high error tolerance. __________________________________________________*****_________________________________________________
