Abstract

A control module () includes a first signal processing unit () that is coupled to a second signal processing unit () by a control bus (), an address bus () and a data bus (). The control module conveys seed value addresses () and expected result addresses () over the address bus, seed values () and verification set output values () over the data bus, and compares each verification set output value to an expected result (), thereby allowing the control module to determine whether the first signal processing unit, the control bus, the address bus, and the data bus are collectively functioning correctly. By properly selecting the seed value addresses, expected result addresses, seed values, and expected results (and correspondingly, verification set output values), proper operation of each line of the address bus and control bus may be individually verified.
