The invention relates to a reinforcing element for an article of clothing, in particular for a goalkeeper glove, that allows a bending in a first direction, but resists bending in a second direction. The reinforcing element includes at least one bending area that has a curvature with a shape that allows bending of the reinforcing element in the first direction and blocks a bending of the reinforcing element in the second direction.

In order to further develop a circuit arrangement (100) as well as a method of processing data to be protected against unauthorized access by means of encryption or decryption, by means of which method the data are stored in at least two memory modules (10, 12) in such way that a flexible configuration of any memory parts as main memory or redundancy memory is enabled, it is proposed to provide at least one real-time configurable redundancy concept for the memory modules (10, 12), by which the data can be stored redundantly in physically separate memory modules (10, 12).

The invention describes a method and an arrangement for writing to NV memories in a controller architecture, together with a corresponding computer program product and a corresponding computer-readable storage medium, which may be used in particular to speed up writing or programming processes in NV code memories of microcontrollers, such as for example smart card controllers. The method consists in extending the instruction set of the controller by so-called MOVCWR (move code write) instructions, which make it possible to write a defined data word (byte) to a defined destination address within an NV code memory. The data word (byte) is here written to the correct position of the cache page register of the respective NV memory and the page address pointer register of the memory is updated with the associated page address. If an MMU (memory management unit) is present, this MOVCWR writing to the cache page register takes place, like MOVC reading or code fetch, under the control of this MMU.
摘要:
A signal interpolator comprises a fractional interpolator and a numeric controlled oscillator. The numeric controlled oscillator may generate a control signal for controlling the fractional interpolator. The numeric controlled oscillator generally comprises a register, a modulo-M device, and an adder. The register may hold a count value, and the modulo-M device may apply a modulo-M function to the count value to generate the control signal therefrom. The adder may add an increment value to the modulo-M signal from the modulo-M device, to update the count value in the register.

To provide an electric or electronic circuit arrangement as well as a method of detecting and/or identifying and/or recording at least an access violation, particularly at least a memory access violation, in a microcontroller provided particularly for a chip card or smart card, with which the source causing this access violation (referred to as break source) as well as the code address occurring upon this violation can be detected and/or identified and/or recorded when an access violation occurs during the program run, the circuit arrangement comprises at least a memory unit; at least an interface unit assigned to the memory unit; at least a processor unit connected to the memory unit particularly via the interface unit for executing instruction codes. These instruction codes can be requested from the interface unit by means of at least a request unit; are run up in at least a fetch or request queue in the request unit; and are decodable by means of at least a decoding unit assigned to the processor unit for running the fetch or request queue, in which a given category of access violation codes is assignable to each given category of access violations. The access violation code replaces the corresponding instruction code, and comprises data such as information on the address, particularly the code address and/or the type and/or the location and/or the source and/or the instant of the access violation.

The invention relates to a method and an arrangement for the verification of NV fuses as well as to a corresponding computer program product and to a corresponding computer-readable storage medium which can be used notably for the detection of attacks on the smart card security which modify EEPROM contents and hence also the contents of EEPROM fuses.During the reset phase the fuses are read from the EEPROM. The fuse values successively read out are then automatically verified. One possible implementation is, for example, to load the fuse values read out into a signature register, followed by comparison with a reference value. Appropriate security measures can be activated should the automatic verification indicate an error, for example, due to unauthorized modification of a fuse or attack on the boot operation.
