Abstract:
One example includes a system. The system includes an error injection system. The error injection system includes an error injector to store a programmable control structure to define a memory error. The error injector being further used to inject the memory error into a respective one of a plurality of memory storage elements associated with a memory system at a predetermined address via an address controller and to determine if the memory error at the predetermined address associated with the respective one of the plurality of memory storage elements is corrected via error-correcting code (ECC) memory associated with the memory system.
Abstract:
A system and method for testing the integrity of a vehicle testing/diagnostic system is provided. Examples of vehicle testing/diagnostic systems may include any equipment (portable or stationary) found in an automotive maintenance and/or testing environment (or other environment) that is capable of communicating with vehicle on-board diagnostic (OBD) systems. Prior to conducting an OBD test on one or more vehicles, an integrity testing system interfaces with a vehicle testing/diagnostic system to determine whether the vehicle testing/diagnostic system is capable of communicating via one or more predetermined communications protocols.
Abstract:
The invention relates to an integrated component (ICT) with at least two core circuits (KK0, KK1) that are of the same type and that can be operated in synchronicity. Said integrated component comprises a comparator unit (VGL) which provides the signals of corresponding outputs (ou0-1, ou1-1; ...; ou0-n, ou1-n) of the core circuits (KK0, KK1) via test inputs (cpi) for their mutual comparison. A hardware fault injector (XR0, XR1) is disposed upstream of said test inputs (cpi) of the comparator unit (VGL) and is controlled via a fault injection input (cx0, cx1).
Abstract:
In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing an error framework for a microprocessor and for a system having such a microprocessor. The error framework may alternatively be implemented by a hardware component, such as a peripheral device for integration into a system. In one embodiment, an error framework of a microprocessor or a hardware component includes an error detection unit to capture an error within the hardware component; a state detection unit to capture error context information when the error is detected within the hardware component; an error event definition unit to define a unique error event representing a combination of the error and the error context information; and a configuration unit to define an error event response based on the unique error event. The error context information may include, for example, a known state of a system at the time the error occurs or a known state of the hardware component or microprocessor within which the error is detected at the time the error occurs.

Abstract:
The invention concerns a method for initialising a serial link between two integrated circuits comprising a parallel-serial port and the device for implementing the method. The method for initialising a serial link between two integrated circuits comprising an input-output port between a parallel bus and a serial link, said port using two clocks of different frequencies, a first one, with higher frequency for the serial link and called transmitting clock (CKT), a second one, with lower frequency for signals coming from the parallel bus and called clock system (CKS). The invention is characterised in that it consists in the following steps: reinitialising the port with isolation of the receiver clock logic; reinitialisation of the transmitting clock logic (CKT); resetting the serial link between the two ports. The invention also concerns an iteration loop process, automatic or dependent on a microprocessor for implementing a bi-directional serial link.
Abstract:
An ECC check result handling circuit (27) for manipulating a check result (14) generated by an ECC circuit (2) is described. The ECC check result handling circuit (27) is operable to receive an ECC check result generated by an ECC circuit and to output a configurable forced ECC check result instead of the ECC check result in response to an occurrence of a predefined condition.
