A method for operating a hardware platform for the inference calculation of a layered neural network. In the method: a first portion of input data which are required for the inference calculation of a first layer of the neural network and redundancy information relating to the input data are read in from an external working memory into an internal working memory of the computing unit; the integrity of the input data is checked based on the redundancy information; in response to the input data here being identified as error-free, the computing unit carries out at least part of the first-layer inference calculation for the input data to obtain a work result; redundancy information for the work result is determined, based which the integrity of the work result can be verified; the work result and the redundancy information are written to the external working memory.

Inference calculation for neural networks with protection against memory errors

A method for encoding and storing digital data, which include a plurality of real values, in a signal processing unit of a radar sensor in which at least one real value r in an exponential representation in the form r=m·bis stored, where m is a digital mantissa having a length p, b is a base, and k is a positive number that is encoded as a digital number having a length q. An exponential representation with b>2 is used for the compressed storage of the values r.

FMCW radar sensor including synchronized high frequency components

A method for authenticating a message transmitted via a communication channel, including the following: sampling recurring signal edges within a data frame of the message, sampling values being obtained with a start time that is offset between the signal edges, reconstructing an average signal characteristic of a part of the message from the sampling values, calculating signal-technical properties of the data frame from the signal characteristic, and the message is authenticated based on the properties.

Method and device for authenticating a message transmitted via a bus

A method for encoding and storing digital data, which include a plurality of real values, in a signal processing unit of a radar sensor. In the method, at least one real value r in an exponential representation in the form r=m&#xb7;bis stored, where m is a digital mantissa having a length p, b is a base, and k is a positive number that is encoded as a digital number having a length q. The values r for the compressed storage are transformed into an exponential representation in the form r=m*&#xb7;b, where m* is the mantissa and f is a function of k that is selected from multiple functions, and the selection of function f takes place based on a value distribution of the values to be stored.

A processor system comprises at least a program counter structure, an interrupt control device, a memory, and an apparatus. The interrupt control device is configured to respond to an interrupt request by providing the program counter structure with an address associated with the interrupt request. The program counter structure is configured to output the address to the memory via a memory interface. The apparatus is configured to protect the program counter structure in case of an interrupt request, the apparatus includes an interface, a comparing device, and an outputting device.

Method and apparatus for protecting a program counter structure of a processor system and for monitoring the handling of an interrupt request

A sensor system for furnishing a D-dimensional measured signal encompasses at least N sensors (where D&#x3c;N) sensors that have measurement directions linearly independent of one another; a stimulus source for furnishing a periodic stimulus signal for each of the sensors, the stimulus signals having mutually orthogonal frequencies; and a processing device for removing the stimulus signals from the sensor signals and for furnishing the D-dimensional measured signal.

Redundant signal capture

A system for checking a program memory) of a processing unit includes a check module, and the processing unit is made up of an instruction counter connected to the check module. The check module has a register connected to a first changeover switch that sets the register content. In a system that allows for the instruction addresses of the entire program memory to be checked, the instruction counter contains an ancillary counter, which runs through the instruction address space of the program memory independently of the program code during normal operation and which is connected to the register.
