BUS APPARATUS WITH DEFAULT SPECULATIVE TRANSACTIONS AND NON-SPECULATIVE EXTENSION

机译:具有默认规范性交易和非规范性扩展的公交设备

摘要

A bus apparatus is provided, which includes a bus master and a bus slave coupled to the bus master through a bus interface. When the bus master sends a bus transaction to the bus slave, the bus slave executes the bus transaction. The bus transaction is speculative by default. The command of the bus transaction indicates whether the bus transaction is a write transaction or a read transaction. When the bus transaction is a write transaction, the bus slave stores the write data of the bus transaction at the address of the bus transaction. When the bus transaction is a read transaction, the bus slave responds the bus transaction with a read data stored at the address of the bus transaction. The bus slave informs the bus master that the bus slave will not recognize further bus transactions in a specific period of time by asserting a bus wait signal.
