A hardware Secure Processing Unit (SPU) is described that can perform both security functions and other information appliance functions using the same set of hardware resources. Because the additional hardware required to support security functions is a relatively small fraction of the overall device hardware, this type of SPU can be competitive with ordinary non-secure CPUs or microcontrollers that perform the same functions. A set of minimal initialization and management hardware and software is added to, e.g., a standard CPU / microcontroller. The additional hardware and / or software creates an SPU environment and performs the functions needed to virtualize the SPU's hardware resources so that they can be shared between security functions and other functions performed by the same CPU.

A differential diameter hole drilling method by which through-holes having improved major surface quality are formed in a target material involves drilling a pilot hole having a diameter that is less than the desired diameter of the through-hole and then drilling a through-hole having the desired diameter. The pilot hole forms a channel from which thermal energy produced during laser drilling can diffuse into the environment, thereby reducing the amount of thermal energy diffusing into the surrounding target material matrix and the degree of thermal damage to the heat affected zone of the target material matrix. The pilot hole also forms a channel through which ablated target material may be removed, thereby increasing overall through-hole throughput. Pilot hole formation reduces the thermal energy required to form the remaining portion of the through-hole and thereby results in less thermal damage to the surrounding target material matrix.
