A cam assembly for an archery bow comprises: a journal for letting out a draw cable as the bow is drawn and the cam assembly rotates; a take-up mechanism for taking up a first power cable; and a let-out mechanism for letting out a second power cable. The first multi-layer substrate stacks up first metal layers, first dielectric layers alternately and has VIAs. All memory locking and address-translation functions are generally performed only once for a queue bank to reduce system overhead.
