Overview

The Synopsys USB 1.1 Controllers support Full and Low Speed based on USB specification from the USB Implementer Forum. The Synopsys USB 1.1 IP offering consists of the USB 1.1 Device and USB 1.1 OHCI Host controllers for integration into SoCs, and Verilog testbench for integration testing. These elements enable quick development of SoC designs incorporating the USB 1.1. The Synopsys USB 1.1 IP is targeted for SoCs requiring the smallest area and lowest power, such as those used in IoT applications.
The DMA in the Device controller and list processor in the Host controller reduce interrupts to the CPU/MPU and bus, reducing power consumption and leaving MIPS and bus bandwidth for other functions.
The Synopsys USB Digital Controllers offer easy integration, reliable data transfer speeds, and low overall power consumption. As the leading supplier of USB IP for more than a decade, Synopsys provides designers with efficient USB IP for cost effective integration into system-on-chip designs. Synopsys’ expertise in developing and supporting USB IP enables us to build a low risk, high quality USB IP solution.

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.
