US Patent 7225373 Data transfer validation system

System and apparatus for data validation is described. An initialization controller includes an initialization state machine. The initialization state machine is configured to cause configuration data to be transferred from memory internal or external to the integrated circuit to other memory internal to the integrated circuit. The configuration data is stored in the integrated circuit, read back from storage in the integrated circuit, and compressed by the integrated circuit after being read back. The configuration data is compressed into a signature, which may be compared with an expected result for the signature.
