A micro-processor 4, memory circuit 5 and control circuit 6, all in 'naked die' form, are combined together on a substrate 'printed' with an electrical circuit to form a single package, hybrid Integrated Circuit capable of executing / storing proprietary programs / data in a secure environment. During normal processor operation, only the internal processor 4 can read from or write to the internal memory 5 prodding protection against unauthorised access to the said memory contents and security for the operation of the system as a whole. The internal memory is 100% end user configurable and is prepared for operation by the end user testing and programming the Device in the PTU (Programming / Testing Unit). Full compatability means no special hardware or software engineering requirement for Device implementation and, due to re-programmability, repeated re-use of the Device in subsequent differing applications. |
