Abstract
A ring bus and a credit allocation method are provided. The ring bus includes a slave module and multiple master modules. The slave module includes an injection table and a state table, and is configured to generate a credit signal including a node identity and an active code. The master modules are coupled to the slave module to form a ring path. The slave module determines whether the credit signal is a newly injected credit signal, and determines the node identity of the credit signal according to the injection table or the state table. The slave module transmits the credit signal to the master module corresponding to the node identity through the ring path according to the node identity. The slave module uses a corresponding idle entry to receive a credit request signal provided by the master device consuming a credit of the credit signal.
