Embodiment Construction

[0020]FIG. 1 depicts an embodiment of a block diagram of a hand-held apparatus 100, such as, a calculator. The apparatus 100 includes a processor 102, support circuit 106, security module 104 and memory 108.

[0021]The processor 102 may be any processor capable of executing computer instructions, such as, instructions stored in the memory 108. The processor 102 may be specific to a hand-held device, calculator or the like, and may be capable of performing algebraic calculation, geometry functions and the like. The processor 102 may include normal and security peripherals that monitor and ensure that the apparatus 100 is tamper-proof, which may be monitored by the security module 104. Herein, tamper proof means that unauthorized code or changes are not allowed, or that at least a portion of the memory or of the settings is protected from unauthorized access.

[0022]The support circuit 106 are circuits that may include, but are not limited to, power supplies, clock circuits, cache memory ...
