An arbiter circuit (100) can include a latch (106) that latches competing input signals (Req_A and Req_B) to generate latch output signals (latn1 and latn2). A filter section (108) can prevent metastable states of latch output signals (latn1 and latn2) from propagating through to output signals (Sel_A and Sel_B). If both input signals (Req_A and Req_B) are activated, a feedback circuit (110) can activate a feedback signal (fb) after a predetermined delay (.delta.), provided both output signals (Sel_A and Sel_B) remain inactive.
An arbiter circuit (100) can include a latch circuit (102) that latches competing input signals (MATCH1 and MATCH2) to generate signals on latch output (110-0 and 110-1). A filter section (104) can prevent metastable states of latch output signals from propagating through to output signals (BUSY2 and BUSY1). In addition, filter section (104) can generate output signals (BUSY2 and BUSY1) having one set of values when both inputs are inactive, and a second set of values when latch (102) is in the metastable state.
