Abstract
A high-integrity multi-core heterogeneous processing environment and methods for high integrity computing on multi-core heterogeneous processing environments are disclosed. A multi-core heterogeneous processing environment may include an application processor with one or more processing cores and an integrity tester for executing integrity kernels on the application processor. The multi-core heterogeneous processing environment may further include an integrity processor having a different architecture than the application processor and an integrity manager operating on the integrity processor. The integrity manager may dynamically generate integrity kernels to test the functionality of the application processor prior to and/or subsequent to the execution of critical programs on the application processor. The integrity manager may identify one or more faults based on a result of the integrity kernel executed on the application processor and may further take corrective action based on identified faults such that an undetected fault rate remains below a selected integrity specification.
