Universal in-band error masking

Abstract:

Embodiments herein describe error interceptors disposed along a bus that communicatively couples first and second circuits for redirecting in-band errors. That is, the error interceptors can block (or mask) in-band errors so they are not forwarded along the bus. Further, the error interceptors can redirect those errors such that they are converted into out-of-band errors. Moreover, the user can select which error interceptors to activate (e.g., block and redirect the errors) and which to deactivate (e.g., permit the in-band errors to pass). In this manner, the user can control which circuits receive in-band errors and which do not based on whether those circuits can handle the in-band errors.
