ABSTRACT:
Signal transactions are conducted between nodes coupled to a bus, without causing bus deadlock during split transactions. Deadlock avoidance is achieved by rendering a node effectively unavailable at such times to serve as a bus slave for a new bus master. When the "locking" node serves as a transaction source, deadlock is avoided by deasserting, during a split transaction, a buffer-available signal, which is used normally to indicate receiver buffer availability. Additionally, when the "locking" node serves as a transaction destination, deadlock is avoided by deasserting a bus-ownership request signal, which is used normally for requesting bus ownership. After completion of the split transactions, such signals may be unmasked.
