CO-PROCESSING UNITS BASED FISCAL CONTROL UNIT

Abstract:

A fiscal control unit system may include a central processor unit that includes a first processing unit and a second processing unit that operates independently of the first processing unit, and isolated from the first processing unit. A buffer module may operate within the first processing unit to provide communication with a fiscal control server and an electronic transaction register and wherein the buffer module may receive transaction registrations from the electronic transaction register. A signing module may operate within the second processing unit, to communicate with the buffer module, and to provide a cryptographic record of transaction registrations received by the buffer module.
