    • A multi-master bus system (10) comprises bus (12), a plurality of bus devices (14, 16, 18, 20, 22, 24), coupled to the bus, including masters (14, 16, 18), and slaves (20, 22, 24), a memory controller (26) for controlling the data exchange on bus (12), having a memory (36) for storing a transaction type value with respect to each slave (20, 22, 24). The multi-master bus system (10) comprises further an arbiter (30) for performing bus arbitration, arbiter (30) having logic for conditionally subsequently granting the bus (12) to a master of an initiating transaction for a closing transaction depending on the transaction type value of the slave of the initiating transaction. The multi-master bus system makes atomic or indivisible transactions possible on a bus without changing the bus width or the bus protocol.
    • 多主总线系统(10)包括总线(12),耦合到总线的多个总线装置(14,16,18,20,22,24),包括主机(14,16,18)和 从机(20,22,24),用于控制总线(12)上的数据交换的存储器控​​制器(26),具有用于存储关于每个从机(20,22,24)的交易类型值的存储器(36) 。 多主总线系统(10)还包括用于执行总线仲裁的仲裁器(30),仲裁器(30)具有逻辑,用于有条件地随后将总线(12)授予终止事务的主机,取决于关闭事务 启动事务的从属事务类型值。 多主总线系统可以在总线上实现原子或不可分割的交易,而无需更改总线宽度或总线协议。
