ABSTRACT:
A test and measurement instrument such as a Logic Analyzer, or the like, has at least one Reloadable Word Recognizer whose reference value can be loaded by a trigger machine with a current acquired data sample while data is being acquired. In a second embodiment useful for performing memory testing, the reloadable word recognizer is used in cooperation with two conventional word recognizers. In a third embodiment, a delay unit is employed to provide delayed input data words as reference words. In a fourth embodiment, an offset register and adder are used to modify the input data words before storing them. A fifth embodiment provides for substantially immediate use of base addresses of relocatable subroutines and stack-based variables recovered from a data stream acquired from a system under test.
