    • An apparatus and method which may be used with a logic analyzer are provided for acquiring groups of data words from the circuitry of a synchronous logic system where each group contains a qualified data word together with a predetermined number of data words which have preceded it. The apparatus includes a circuit for detecting the qualified word and a data storage device having a plurality of separately-addressable storage locations. Both the qualified data detector and the storage device are logically connected to the synchronous logic circuitry. The apparatus further includes an addressing circuit which responds to the detection of a qualified word and to the presence of data words on the synchronous logic circuitry by producing storage addresses which are provided to the storage device for storing the data word groups in successive storage locations. In an alternative embodiment, the addressing means responds to qualified word detection and to the number of data words stored in the storage locations such that each stored group of data words contains a qualified word and a respective number of data words.
    • 提供了可以与逻辑分析器一起使用的装置和方法,用于从同步逻辑系统的电路中获取数据字组,其中每个组包含限定数据字以及其之前的预定数量的数据字。 该装置包括用于检测合格字的电路和具有多个可单独寻址的存储位置的数据存储装置。 合格数据检测器和存储设备都逻辑连接到同步逻辑电路。 该装置还包括寻址电路,其通过产生提供给存储装置的用于在连续存储位置中存储数据字组的存储地址来响应对合格字的检测和数据字的存在。 在替代实施例中,寻址装置响应于合格的字检测和存储在存储位置中的数据字的数量,使得每个存储的数据字组包含合格字和相应数量的数据字。
