Abstract: A method is disclosed for exchanging data between a central processing unit (CPU) and an input/output processor (IOP). The CPU and IOP may both be senders or receivers depending on whether data is flowing to or from the CPU. Where data is flowing to the CPU, the CPU is the receiver and the IOP is the sender. Where data is flowing from the CPU, the CPU is the sender and the IOP is the receiver. A sender evaluates the amount of empty buffers and, in a preferred embodiment, whether there is more data coming to determine whether to release partially full buffers in its buffer pool. Partially full buffers may be released based on any threshold as desired from a simple integer to a complex algorithm. The evaluation of whether to release partially full buffers is preferably implemented where a sender obtains at least one data packet for sending to a receiver and where a sender obtains an empty buffer from a receiver.

Abstract: Methods of administering a game in a wireless embodiment utilizing failure fallback and recovery between automatic and manual modes is disclosed. In one embodiment, a remote game device listens for a game state message and verifies the presence and signal strength of a game state message. If the signal strength is weak or there is no signal, the remote game device transitions to a manual mode to allow a user to manually update game state and continue play in an uninterrupted manner. Once signals of sufficient strength are received, the remote game device transitions from the manual mode to an automatic mode.
