Overview

The DUSB2 is hardware implementation of full/high-speed peripheral controller that interfaces to the UTMI bus transceiver. The DUSB2 contains the USB PID and address recognition logic, state machines to handle USB packets and transactions, endpoints number recognition logic and endpoints FIFO control logic. The DUSB2 is designed to support 12 Mb/s "Full Speed" (FS) and 480 Mb/s "High Speed" (HS) serial data transmission rates. The design is technology independent and thus can be implemented in a variety of process technologies. This core strictly conforms to the USB Specification v2.0. The DUSB2 core is delivered with fully automated test bench and complete set of tests, allowing easy package validation at each stage of SoC design flow.

D32PRO, scalable & royalty free 32-bit CPU

D32PRO is one of the newest 32-bit CPUs available on the market. It’s been designed by Digital Core Design, IP Core provider and SoC design house from Poland, responsible e.g. for the world’s fastest or world’s smallest 8051 CPU. DCD launched more than 70 different architectures since 1999, which have been implemented in more than 300 000 000 electronic devices, that’s why one can be sure that quite considerable experience stands behind the D32PRO.

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.
