Apparatus for measuring the speed of transmission of digital characters

摘要

An apparatus for capturing data outputted by a data processing unit includes an interface unit for generating a strobe pulse for each data word outputted, a timer for measuring the elasped time between the occurrence of two consecutive data words and a DMA controller for storing the data words together with the elapsed time data words in a remote storage unit. A time-out circuit insures that the time measured is between the occurrence of the first and second data words of each pair of data words.
