Abstract
Method and apparatus for data transfer validation is described. Configuration data is obtained. A signature for the configuration data is generated. The configuration data and the signature are stored in a first memory. The configuration data is transferred to a second memory for storage. The configuration data transferred is read to generate another signature, where the other signature is for the configuration data transferred. The configuration data read is compressed to provide the other signature. The signature is transferred for comparison with the other signature to validate whether the configuration data transferred was transferred without error. The method and apparatus may be used when transferring configuration data, including, but not limited to, transfer of configuration data from a memory to a programmable logic device.
