Serial data correlator/code translator

Claim 1

A system for analyzing asynchronous signals containing bits of information for ensuring the validity of said signals comprising: (a) a bit sampling means having a first input receiving said signals to be analyzed and an output; (b) clock means connected to said bit sampling means for causing said bit sampling means to sample each bit of information supplied thereto a plurality of times producing a plurality of sampled signals; (c) a sequence controller means connected to the output of said bit sampling means; (d) a plurality of programs stored in said sequence controller means representing maps having a plurality of sequence steps; (e) means for feeding said sampled signals to said sequence controller means and for sequentially stepping said sampled bits through said plurality of steps of said maps; (f) said sequence controller means generating coded signals identifying the steps as said sampled signals are stepped therethrough; (g) a storage register means having a plurality of input terminals and output terminals; (h) means for connecting said input terminals of said storage register means to said sequence controller for receiving coded signals from said sequence controller indicating the step that said sequence controller is in, (i) means for connecting said output terminals of said storage register means to said sequence controller means; (j) said storage register means generating signals identifying the sequence step that said sequence controller is operating in and supplying this signal back to said sequence controller means for controlling the sequential stepping of the sequence controller means as additional pieces of sampled bits are received; and (k) a data decoder means connected to said output terminals of said storage register means for decoding said signals generated by said storage register and producing predetermined output signals indicating that a particular step has been reached in said sequence controller.
