Abstract

An integrated circuit (IC) performs error detection and correction on configuration data. The IC includes a configuration memory for storing configuration data and error correction data, and error correction circuitry for receiving the configuration data, correcting a particular error in the received configuration data when the particular error exists in the configuration data, and outputting the configuration data without the particular error. The IC further includes a configurable circuit (e.g., a configurable logic circuit or a configurable interconnect circuit) that receives the error-corrected configuration data from the error correction circuitry, and circuitry to write the corrected configuration data and error data back into the configuration memory.
