Overview

USB 5G, 10G Dual Mode controller is a highly configurable core and implements the USB Host functionality or USB Device functionality selectable via a register or an external pin. The host/device core can be interfaced with third party USB PHY.

The Dual mode controller supports Host functionality using high performance DMA engine based on xHCI specification exposing either an AHB or AXI interface. The host mode core can be configured to support full fledged xHCI implementations for use in standard PCIe-USB bus adaptors/chip sets or be configured with a subset of features for embedded applications requiring limited host functionality. The dual mode controller supports Device functionality which operates in a cut through mode exposing a native packet interface or exposes either an AHB or AXI interface and including a high performance proprietary DMA engine.

The Dual Mode Controller core is carefully partitioned to support standard power management schemes which include extensive clock gating and multiple power wells for aggressive power savings required for mobile and handheld applications.

The controller has a very simple application interface which can be easily adapted to standard on-chip-bus interfaces such as AXI, AHB, OCP as well as other standard off-chip interconnects making it easy to be integrated in a wide range of applications.

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.
