Method and device for monitoring an electronic circuit

For monitoring method and device for electronic controller, sign at least one memory all data a fixed in the other capable of the ECC unit for memory is filled very much rapidly and checks the wireless, and is needed time-consumingly to the processing unit transmits the whole data, ECC check of a memory multiple memory cells data, and can be is formed with reading word of multiple, wherein the ECC check data width and additional information respectively, and for wherein the memory, and an, therefore of continue access and withdraw of the indication according to be a uses the manner to and fully code at least one memory/Data region, namely flow processor is a t-shaped storing unit and each of content, a memory a whole ECC check method of ECC device with one additional information, and a control information of the whole ECC check width's data, and additional information for controlling information of the ECC unit and a storage for comparing.
