Abstract: A method includes executing an application of a scripting language. The application of the scripting language uses first and second packages of an application programming interface (API). The first and second packages extend to each other. The method includes, from a class of the first package, calling and executing first native code of the API to implement a function of a method of the class of the first package. The first native code is in a programming language different from the scripting language. The executing the first native code of the API includes calling a method of a class of the second package. The called method of the class of the second package is executed using a virtual machine of the scripting language. The application of the scripting language may be a Java card application, and the programming language may be a C programming language.

Abstract: A method comprises receiving an input clock signal having a clock frequency band between a lower frequency limit value and an upper frequency limit value, dividing the clock frequency band in a set of frequency ranges having a set of frequency limit values that include the lower frequency limit value and the upper frequency limit value, comparing the frequency of the clock signal with the set of frequency limit values to produce comparison indicators having a first logic value when the measured frequency fails to exceed at least one frequency limit value and having a second logic value when the measured frequency exceeds the at least one frequency limit value, and, as a result of at least one of the logic values of comparison indicators having the second logic value, producing a global flag signal indicating that the measured frequency falls outside of a frequency range.

Abstract: A hardware network accelerator comprises a plurality of Ethernet communication interfaces, a plurality of memories, and a further memory. Each memory stores records comprising destination IP data identifying a destination IP address range. The further memory stores further records, wherein each record comprises next-hop data indicating a next-hop IP address, next-hop enable data, and network port data indicating an Ethernet communication interface. Each Ethernet communication interface is configured to obtain an IP packet, access in parallel the memories in order to read the records, select a record having a destination IP address range containing the destination IP address of the IP packet, read the further record associated with the selected record from the further memory, and select the indicated Ethernet communication interface. The selected Ethernet communication interface is configured to transmit an Ethernet frame comprising the IP packet based on the next-hop enable data and next-hop data.

Abstract: An etched leadframe includes separated frame portions, where each frame portion includes an intermediate region interposed between lead and die pad regions. An integrated circuit die is mounted to each die pad region. A clip is mounted to each integrated circuit die, wherein the clip includes a lead mounting portion mounted to the lead region of an adjacent frame portion and a bridge portion extending over the intermediate region of the adjacent frame portion and mounted to the die pad region of the adjacent frame portion. A first cut made through the frame portion of each etched leadframe at the intermediate region separates the lead and die pad regions without severing the bridge portion of each clip. A conductive layer is plated on full sidewalls of the lead and die pad regions exposed by the first cut. A second cut is then made through the bridge portion of each clip.

Abstract: A processing device includes memory circuitry having stored therein a set of weight values and a threshold value and instructions which, when executed in the processing device, cause the processing device to apply a first artificial neural network (ANN) processing to a set of sensing signals, producing as a result a set of compressed representations of the sensing signals. The first ANN processing is trained to produce the set of compressed representations using a set of training signals distributed according to a set of training classes having an integer number L of classes. The instructions further cause the processing device to configure weight values of a plurality of computing units of a set of ANN processing circuits as a function of a set of weight values.

Abstract: A system includes a memory formed by memory units accessible in write mode and in read mode. Each memory unit includes an array of memory cells and a peripheral circuit of access to the memory cells. Each memory unit is configurable in a first operating mode and a second operating mode. The array of memory cells are set in the first operating mode and the second operating modes to retain data until a subsequent powering off of the memory unit. The peripheral circuit is powered in the first operating mode and is not powered in the second operating mode. A controller configures any memory unit of the memory having undergone no write or read access for a determined time period to be in the second operating mode.

Abstract: A sensor unit is coupled to a machine and configured to detect anomalous behavior of the machine. The sensor unit includes a low power microcontroller that learns to recognize a plurality of operations of the machine. The sensor unit generates mean vector and inverse of a Cholesky decomposition matrix for each operation. During a detection mode the sensor unit computes a Mahalanobis distance for each feature vector, mean vector and first matrix. The sensor unit detects anomalous behavior or classifies the operation of the machine based on the Mahalanobis distances.

Abstract: An authentication method is used in pairing a peripheral device to a companion device. The peripheral device sends a first identifier and a first value of a first counter to the companion device. The companion device verifies whether a pairing table stored in the companion device contains the first identifier. When the pairing table does not include the first identifier the companion device initiates a pairing session. When the pairing table includes the first identifier, the companion device compares the first value to a second value associated with the first identifier in the pairing table. In response to the first value being greater than the second value, the companion devices initiates a nominal session and in response to the first value being lower than or equal to the second value, execution of the method is stopped.

Abstract: According to an embodiment, a regression analysis is performed on a subset of a dataset, where the subset of the dataset corresponds to inputs from a first row of a matrix of sensors at a time instant k. The regression analysis generates a set of coefficients. A filter transform, to be applied on the subset of the dataset, is determined based on a comparison between the set of coefficients and threshold values. The filter transform can be one of an infinite impulse response (IIR) filter transform, a first-order filter transform, or a second-order filter transform. Once the filter transform is determined, it is applied to the subset of the dataset to generate a first output matrix.
