Abstract
An arbiter based on pairwise mutual exclusion produces an absolute priority signal (G) indicating that one of three or more requests (R.sub.1, R.sub.2, . . . R.sub.N) has gained absolute priority over all the other. At least one mutual-exclusion element (20.sub.1 or 20p) in the arbiter is designed so that its pairwise priority determination car be reversed in response to at least one externally originated test signal (T.sub.1, T.sub.2 or T.sub.M-1, T.sub.M). By doing so after the requests have been asserted in a specified order, a priority conflict can be generated among the requests in order to check the conflict-resolution capability of the arbiter.
