    Abstract: A control device for a vehicle engine includes a memory unit for storing engine configuration parameters, a processing unit for sending control signals to the engine in accordance with the configuration parameters, and an input/output unit connectible to an external computer to modify the configuration parameters. The control device includes a first portion and a second portion of the memory unit, with each portion being alternately used in an active state for storing a current version of the configuration parameters or in an inactive state for the writing of a new version of the configuration parameters. The processing unit accesses the portion which is in the active state for reading, and the input/output unit accesses the portion which is in the inactive state for writing. An interconnection unit selectively switches one of the portions to the active state and the other of the portions to the inactive state.

    Abstract: A serial interface for communicating with peripherals may include a circuit for generating pointers to addresses in sections of a memory, and a circuit for serially transferring data from or to at least one peripheral connected to the interface that is coupled to the memory based upon requisite configuration commands. The interface may further include a control register coupled to the memory and to the serial transfer circuit for controlling data to be transmitted or received. The interface does not require that an external controller provide configuration commands each time data is transmitted or received because the memory sections for storing data may be divided in distinct memory spaces. That is, each memory space may store data for a respective peripheral connected to the interface. Moreover, another memory section may be used to store all of the configuration commands of the interface required for communicating with the peripherals.

    Abstract: An integrated circuit includes an input pad for receiving an externally generated analog signal, and a pre-sampling circuit for pre-sampling at least one internally generated analog reference signal. An analog-to-digital converter is connected to the input pad for providing a numerical value of the externally generated analog signal, and is connected to the pre-sampling circuit for providing a numerical value of the internally generated analog reference signal. A fault signaling circuit is connected to the pre-sampling circuit and to the analog-to-digital converter for generating a fault signal when the numerical value of the externally generated analog signal is equal to the numerical value of the internally generated analog reference signal. The fault signal indicates that an electrical connection providing the externally generated analog signal to the input pad is faulty.

    Abstract: A method whereby the N elements of a memory are read sequentially, and the data items contained therein are compared with reference data items. Simultaneously with the reading of each element of the memory, its address is written in a number of redundancy check registers, each connected to a respective redundancy element. In the event the element of the memory differs from the reference data item, the first of the redundancy check registers is blocked to prevent it from being overwritten and the address of a faulty element of the memory is permanently stored. Upon the entire memory being read, the addresses of any faulty elements in the memory are thus already stored in the redundancy check registers.
