Out-of-order transaction completion: 使用AXI 可以实现无序事务完成。AXI协议包含事务标识,不限制不同ID值事务的完成。这意味着单个物理端口可以通过充当多个逻辑端口来支持无序事务,每个逻辑端口按顺序处理其事务。 Burst transactions based on start address: AXI manager 只发布第一次传输的起始地址。对于任何后续传...
Outstanding深度是指Master发出的正在进行的命令数量,显然这需要Master和Slave准备更大的buffer来保存这些命令信息。 Out-of-order乱序传输 AXI拥有事务ID,因此支持Out-of-order乱序传输,Out-of-order传输是指后发送的命令对应的数据可以先回来,注意必须是不同ID之间,相同ID之间不能乱序传输数据。例如顺序发送cmd_A和cmd...
而这样的操作,由于slave 返回数据的先后可能不按照master 发出控制的先后进行(Flexible relationship between the write address and data---AXI主要特征三),导致出现了乱序操作(out of order---AXI主要特征五 ),让master最快收到想要的响应。同时,AXI还支持不对齐传输(unaligned data transfers---AXI主要特征四)。A...
• 支持outstanding功能,可以发送多个地址进行读写 • 支持out-of-order传输 • Permits easy addition of register stages to provide timing closure AXI 协议包括: • AXI4-Lite:是AXI4协议的子集,用于简单的控制寄存器类型接口的组件互联 • AXI5-Lite:是AXI5协议的子集,使用AXI5协议特性,用于简单的控...

同时对于master,需要对不同的地址和slave就⾏访问,所以可以对不同的slave 连续操作。⽽这样的操作,由于slave 返回数据的先后可能不按照master 发出控制的先后进⾏(Flexible relationship between the write address and data---AXI主要特征三),导致出现了乱序操作(out of order---AXI主要特征五 ),让master最...
2)Burst-based transactions,只有首地址issued;(burst首地址之后的地址,slave来产生) 3)能够进行multiple outstanding address的发送;(outstanding FIFO与reorder FIFO不一样) 4)能够以out-of-order的方式,完成transaction;(应该outstanding的FIFO大于reorder的FIFO depth) ...
