Abstract:
1. A data transfer validation system, comprising: a first array of memory cells for storing configuration data and a first signature of the configuration data; a programmable logic device externally or internally coupled to the first array of memory cells for transfer of the configuration data and the first signature to the programmable logic device, the programmable logic device having a second array of memory cells, an array of sense amplifiers and a configuration register, the second array of memory cells for storing the configuration data transferred from the first array of memory cells, the configuration register configured to generate a second signature from the configuration data transferred; wherein the configuration resister is configured to compress the configuration data obtained from the second array of memory cells into the second signature for comparison with the first signature; and wherein the configuration register does not have to be seeded to compress the configuration data obtained from the second array of memory cells into the second signature.
