ABSTRACT:
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.
