The company was founded in 1999 and since the very beginning has been focused on IP Core architecture improvements. Our innovative, silicon proven solutions have been employed by over 300 customers and with more than 500 hundred licenses sold to companies like Intel, Siemens, Philips, General Electric, Sony and Toyota. Based on more than 70 different architectures, starting from serial interfaces to advanced microcontrollers and SoCs, we are designing solutions tailored to your needs. IP CORE OVERVIEW The DUSB2 is a hardware implementation of a full/high-speed peripheral controller that interfaces to an UTMI bus transceiver. The DUSB2 contains a 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 v 2.0. It is delivered with fully automated test bench and complete set of tests, allowing easy package validation at each stage of SoC design flow. ● ● ● ● ● ● ● ● ● ● CONFIGURATION At the synthesis level, the following parameters of the DUSB2 core can be easily adjusted to requirements of a dedicated application and technology. The CPU interface is configurable as 8, 16 or 32-bit wide. Each data endpoint can be effortlessly enabled and disabled, by simply changing an appropriate constant in the package file. There is no need to change any parts of the code, to prepare DUSB2 core with requested number of data endpoints.
