Separate memories and address busses to store data and signature

A programmable device employs an address and data corruption logic for data written to a first memory. A first signature is computed from the data stored in the first memory and stored in a second memory. When data is read from the first memory, the first signature stored in the second memory is rea...

Zusammenfassung:	A programmable device employs an address and data corruption logic for data written to a first memory. A first signature is computed from the data stored in the first memory and stored in a second memory. When data is read from the first memory, the first signature stored in the second memory is read and compared with a second signature computed from the data read from the first memory. If the first and second signatures do not match, an error condition is indicated.
