USB 3.0 OTG High / Full / Low- Speed Dual Role IP Core

Overview

Key Features

• Support SW controlled host/device role switching.
• Support Superspeed, Highspeed and Fullspeed
• Support Control, Bulk, Interrupt and Isochronous Transfer Types
• Support U1/U2/U3 power saving modes for USB 3.x port
• Support L1/L2 power saving modes for USB 2.0 port
• Support Hardware LMP Capability and BESL LMP Capability for USB 2.0 ports in host mode
• Support MSI/MSI-X Interrupts and Legacy Interrupt
• Fully Support for Isochronous Transfer error handling, support error conditions like Isochronous Buffer Overrun, Bandwidth Overrun, Missed Service Error, Ring Overrun/Underrun, Parameter Error, etc. in host mode
• Fully Support for Event Data TRB, multiple Event TRBs can be used in one TD in host mode
• Fully Support for Hardware Bandwidth Management, support error conditions like Resource Error, Bandwidth Error and Secondary
• Bandwidth Error in host mode
• xHCI-like ring management, TRB definitions and doorbell mechanism in device mode
• Low-MIPS Operational Model.
• Pipelined transfer mechanism to achieve continuous data streaming
• Fully Support for Scatter-and-Gather, all TRBs can points to byte-aligned buffers without alignment limitation
• Innovative Active TRB Prefetching technology to eliminate TRB access latency and improve system performance
• Dynamically reconfigurable Endpoint type, software can reconfigure the same Physical Endpoint to operate as Bulk, Interrupt or Isochronous EP
• Dynamic data buffer allocation for all endpoints, Tx/Rx Data Buffers can be shared by endpoints to optimize RAM usage
• Configurable number of supported device slots (up to 64) in host mode
• Configurable number of supported active Endpoints (up to 128) in host mode and Device mode
• Configurable numbers of USB 3.x ports and USB 2.0 ports respectively in host mode
• Configurable system bus type (AXI4/AXI3/AHB/APB) and width
• Configurable USB 3.x/2.0 PHY type (PIPE/UTMI+/ULPI) and width.
