Bus analyzer

From Wikipedia, the free encyclopedia

A bus analyzer is a computer bus analysis tool, often a combination of hardware and software, used during development of hardware or device drivers for a specific bus, diagnosing bus or device failures, or reverse engineering. The bus analyzer monitors the bus traffic and decodes and displays the data. It is essentially a logic analyzer with some additional knowledge of the underlying bus traffic characteristics. Analyzers are now available for virtually all existing computer bus standards and form factors such as PCI, CompactPCI, PCI Express, PMC, VMEbus, etc.
