Abstract
A signature capture and analysis system suitable for use in a high performance computer graphics system is described. The system employs a distributed network of signature analysis registers (SARs) which may be configured to capture and accumulate information from one or more channels of data over pre-defined periods of time. The SARs may be so distributed to allow for the isolation of faults to a sub-system level. The signature values developed in these SARs are, in some cases pre-seeded, and may include contributions from both data and control signals. Checking of the signature values against known good or expected outcomes is provided for. In some cases the SARs may be implemented as linear hybrid cellular automatons.
