USBHostSlave is a USB 1.1 host and Device IP core. – Supports full speed (12Mbps) and low speed (1.5Mbps) operation. – USB Device has four endpoints, each with their own independent FIFO. – Supports the four types of USB data transfer control,

USB 1.1 slave/device IP core. Default configuration is 6 endpoints: 1 Control, 1 Isochronous IN, 1, Isochronous Out, 1 Bulk IN, 1 Bulk Out, 1 Interrupt IN. Includes control engine, providing full enumeration process in hardware - no external mi

Wishbone规范具有如下特点:简单、紧凑，需要很少的逻辑门 完整的普通数据据传输总线协议，包括单个读写、快传输、读一修改一写周期、事件周期 数据总线宽度可以是8-64位 支持大端(big-endian)和小端(litle-endian)，接口自动完成两者之间的转换。支持存储器映射、FIFO存储器、交叉互联 握手协议，允许速率控制 可以达到每个时钟周期进行一次数据传输 支持普通周期结束、重试结束、错误结束等总线周期形式 支持用户自定义的标志:采用MASTER/SLAVE体系结构 支持多点进程(
