Overview

USB 1.1 Device Controller IP is based on the latest USB 1.1 specification from USB Implementer Forum (USB-IF) and is compatible with the latest xHCI 1.1 specification. It supports FullSpeed (12Mbps) link speed, and backward compatible with and LowSpeed (1.5Mbps). USB 1.1 Controller IPs are based on a unified architecture which is designed directly for USB 1.1 specification and optimized intensively for logic sharing.

Key features

  • Compatible with xHCI v1.1 specification
  • Compatible with Standard Linux xHCI controller driver
  • Support Fullspeed and Lowspeed
  • Support Control, Bulk, Interrupt and Isochronous Transfer Types
  • xHCI-like ring management, TRB definitions and doorbell mechanism
  • Low-MIPS Operational Model. All data transfers, flow control, ERDY generation are handled by hardware, software only needs to prepare transfer TDs and collect events when transfer is done
  • Pipelined transfer mechanism to achieve continuous data streaming
  • 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
  • Dynamically assigned Endpoint ID, software can reconfigure the same Physical Endpoint with different Endpoint IDs
  • Dynamic data buffer allocation for all endpoints, Tx/Rx Data Buffers can be shared by endpoints to optimize RAM usage
  • Configurable system bus type (AXI4/AXI3/AHB/APB) and width
  • Configurable PHY type (PIPE/UTMI+/ULPI) and width
  • Configurable number of Event Rings and interrupts
  • Configurable number of supported Endpoints
  • Configurable TX/RX Data Buffer sizes to trade-off between performance and area

What’s Included?

What Designers Need to Know About USB Low-Power States

In addition to performance and interoperability, achieving low power has been one of the requirements for industry standards specifications. Some of the key specifications like Universal Serial Bus (USB), PCI Express (PCIe), and MIPI have defined power saving features for burst traffic. This whitepaper explains how Synopsys USB IP offers low power using various low power states that go beyond the basic features.
