A programmable vehicle or engine diagnostic tool includes an interface for receiving a signal relating to a performance parameter of the vehicle or engine, a user interface, and a central processing unit, for processing the signal to generate information for presentation to the user. To facilitate fast boot yet enable re-programming of the diagnostic tool, the system utilizes a non-volatile random access memory main memory for the processor based tool, to store the programming for execution by the central processing unit. Disclosed examples of suitable memories include magnetoresistive random access memory (MRAM), carbon nanotube random access memory (CN-RAM) and programmable metallization memory cell (PMC) memory.
L'invention concerne un outil de diagnostic programmable pour véhicule ou moteur, comprenant une interface qui permet la réception d'un signal associé à un paramètre de performance du véhicule ou du moteur, une interface utilisateur, et une unité centrale permettant de traiter le signal afin de générer une information à présenter à l'utilisateur. Afin de faciliter un amorçage rapide et de permettre néanmoins une reprogrammation de l'outil de diagnostic, ce système comprend une mémoire principale de type mémoire vive rémanente pour l'outil processeur, qui permet de mémoriser la programmation en vue de son exécution par l'unité centrale. Les mémoires adéquates citées dans la description comprennent les mémoires vives magnétorésistives (MRAM), les mémoires vives à nanotubes de carbone (CN-RAM), et les mémoires PMCm (programmable metallization cell memory).
