摘要：
An arrangement (1301-130p) and method based on an on-chip mechanism to increase the amount of information that can be presented for a given sized diagnostic port (120) by Exclusive-OR compression. It allows the possibility of monitoring an entire internal bus in fewer test runs whilst at the same time making more of the diagnostic port available for tracing control signals. It can reduce the time needed to determine the cause of a chip-related problem.
