下面给出本项目的顶层设计架构,其中sram_top为顶层模块,其下包含sram_interface模块以及SRAM_core两个子模块 sram_interface模块:本质是AHB总线上的slave接口,起到连接总线与SRAM存储体的作用,具体来说: 将HCLK,HRESETn,HTRANS,HBURST,HWRITE,HWDATA这些来自于AHB总线的信号转化为存储器接口信号 接收存储器8位读数据...
SPI总线协议(Serial Peripheral Interface) 第一个时钟沿采样,CPHA=1,在每个周期的第二个时钟沿采样。 --- 作者:ivy_reny来源:CSDN原文:https://blog.csdn.net...SPI的通信原理很简单,它以主从方式工作,这种模式通常有一个主设备和一个或多个从设备,需要至少4根线,事实上3根也可以(单向传输时)。也是所有基...

Various types of data interfaces such as register, interrupt, SRAM and FIFO are provided with high configurability. The performance and reusability are both considered. This AHB interface component was successfully applied to chips for DAB and DRM receivers. A typical application of this component ...
连接组件和从模块:内部flash、内部SRAM、AHB2/APB桥、APB外设之间的接口 如下图给出一个典型的AMBA系统: 从图中可以看出AHB/ASB总线到APB总线需要通过桥接器(Bridge)进行连接。 1.APB总线介绍 对比与AHB总线协议,APB应用于慢速外设,不需要AHB总线体系的Arbiter和Decoder ...
支持32位的AHB slave interface(不支持该总线busy传输类型); 支持eFlash的多周期读、写、页擦操作(2块独立的eFlash串联封装); eFlash操作可配置(时序、功能)(flash的异步操作); 支持eFlash中的boot区空间的擦写保护。 1.1 功能框图 eFlash控制器由以下模块组成: flash与AHB总线的接口模块(flash_ahb_if):接收...
