Avalon-ST总线时序图 这个时序图中的ready一直为高的原因:是因为我们在模块间使用Avalon-ST总线时,当Source发数据时一般都会保证接收端Sink已经准备好接收端准准备好收数据,ready时间一般都比发送时间长。 这个时序图中可以很好的解释Avalon-ST总线的原理,来自Sink的ready拉高后,Source对应的valid、sop、eop、channel、d...

·Avalon Streaming Components—典型使用 Avalon-ST 接口的系统联合多功能 模块,称作组件。系统设计器配置组件和把它们连接在一起来实现一个系统。 ·Source and Sink Interfaces and Connections—当两个组件已连接,数据从 源接口流向汇点接口。把源接口连接到汇点接口的组合称作连接关系。 ·Backpressure—Backpressure...
2.Passing channel to Avalon-ST demultiplexer Q:I am trying to build a component, which will be connected toAvalon-STdemultiplexer. Since the data has to be switched between inputs, I've added aso_channel signal. The SOPC builder complains, that source max channel is 0 and sink has max ...
在最近的一次版本更新中,Altera将原来的Avalon接口规范升级到最新的3.2版,并将其改名为Avalon-MM(AvalonMemoryMappedInterface,以下均简称Avalon-MM)接口规范,同时推出新的Avalon-ST(AvalonStreamingInterface)接口规范,因此最新的Avalon总线标准成成为一套拥有Avalon-MM和Avalon-ST两套分支标准的SOPC总线规范。在最近的几次...

Defines the number of transfers that the sink can capture after ready is deasserted. When readyAllowance = 0, the sink cannot accept any transfers after ready is deasserted. If readyAllowance = <n> where <n> is greater than 0, the sink can accept up to <n> trans...
