Abstract
An integrated circuit having a plurality of functional circuits interconnected via a functional bus is provided with a diagnostic bus-master circuit which uses bus transactions on the functional bus to perform diagnostic operations. These diagnostic operations can be performed in real time during normal speed operation of the integrated circuit to produce more accurate diagnostic results. The diagnostic bus-master circuit is particularly useful for reading data values from memory or writing data values to memory as part of diagnostic operations.
