摘要: A single chip processor for use in a smart card has a plurality of instruction memory areas and a processor. Different instructions sets are selectively executable in response to a signal defining a memory area from which instructions are supplied. Preferably instruction and data memory areas are addressable as pages, wherein a page address cannot be directly accessed by a subset of instructions. The processor may include a central processing unit and a cryptographic logic unit which operate at different times and share common instruction memory and sequencing logic. Instructions are supplied to said cryptographic logic unit at an integer multiple of the rate at which they are supplied to said central processing unit.

摘要: A wear-resistant tool insert for machines used in the manufacture of nails, screws, rivets and similar items from a wire starting material. The tool insert is of divided design in the axial direction of the supplied wire. Thus, during application of the tool insert it can "flex" in a controlled manner thereby reducing tensile stress in the tool insert, and reducing the possibility of fracture or breakage of the tool insert, when employed in an overload condition with unacceptably large tensile loads.
