Device, method, and apparatus for selecting address words using digital

Abstract

A device for the selection of address words each having n bit locations and serving for addressing m different receiving locations of a digital communication module, in at least one of the receiving locations, including a digital acceptance module through which address words can be selected. The device has an address word segmenting module through which each address word received by the receiving location can be subdivided into s address word segments with b segment bit locations each, wherein b=n/s and n is an integral multiple of s. The device further has z digital segment filters whose inputs can each be fed with an address word segment, with each segment filter having the function of examining one address word segment each with respect to conformity with a predetermined segment bit pattern, and a filter output signal being available at the output of the respective segment filter, which in accordance with the examination result is either a conformity signal or a non-conformity signal. Additionally, the device has an activation module through which those segment filters can be activated during the duration of the respective address word segment to be assessed which carry out an examination with respect to such segment bit patterns which can occur in the address words acceptable for the receiving location in consideration, in the respective address word segment to be assessed. Finally, an evaluation module through which the output signals of the respective segment filters activated for the assessment of an address word can be evaluated with respect to the presence of an address word that is acceptable for the receiving location in consideration.
