Systems and methods for in-line functional testing of error correcting code functions

Abstract

Systems and methods for error correcting code ("ECC") error handling are described herein. In one aspect, the systems and methods can operate ECC functions on raw data. The ECC function may include generating ECC syndrome data by the ECC syndrome data generation module. ECC syndrome data can be derived from raw data. The system and method can further inject errors based on ECC syndrome data or raw data. The system and method may further determine whether an ECC error detected by the ECC checker corresponds to a failure of the ECC function or to an error based on ECC syndrome data or raw data injection.

Description

[0001] claim priority [0002] This patent application claims priority to U.S. Nonprovisional Application No. 15 / 838,777, filed December 12, 2017, entitled "SYSTEM AND METHOD FORONLINE FUNCTIONAL TESTING FOR ERROR-CORRECTING CODE FUNCTION," which has been assigned to this application assignee and is expressly incorporated herein by reference. technical field [0003] In general terms, the present disclosure relates to systems and methods for in-line functional testing for error detection and correction functions. Background technique [0004] The automotive industry is changing in part as the power source for vehicles is shifting from utilizing fossil fuels to utilizing renewable fuels (eg, electricity). More vehicles are utilizing Advanced Driver Assistance Systems (“ADAS”), which provide different levels of driver assistance (e.g., Adaptive Cruise Control (“ACC”), Forward Collision Warning (“FCW”), etc.) . [0005] As more and more vehicles are equipped with electric mo...

Problems solved by technology

Unlike traditional operating environments, circuits in vehicles may not be tested offline to determine the accuracy of data stored in their subsystems

For example, a vehicle may be participating in a complex ADAS-based use case that does not have sufficient offline time for testing (which includes but is not limited to possible data recovery)
