Mentor supports TI DSPs and MCUs
Mentor Graphics is the first to reach agreement with Texas Instruments to deliver coverification processor support packages (PSPs) for Texas Instruments DSP and microcontroller solutions.
In addition, Mentor Graphics has produced a reference design that demonstrates proof of function to help minimise new product development risk.
The On-The-Go supplement to the USB 2.0 specification has been introduced to provide portable devices with a cost-effective way of conducting point-to-point communications through using USB protocols.
The specification allows applications, such as mobile phones, PDAs, digital cameras and MP3 audio players to connect directly to a peripheral device facilitating point-to-point file exchange without the need of a host PC.

Board timing analysis tool upgraded
Mentor Graphics and Altera have jointly announced support for the STAMP timing file format, allowing PLD and PCB designers to easily share PLD timing data for efficient board-level timing analysis.
At the same time, the additions to the existing USB specification are minimised to ensure interoperability with the approximately 900 million USB-based products in use today.
The soft IP core and evaluation board are the semiconductor design industry's first deliverables from an IP provider for the USB On-The-Go specification.
The evaluation board demonstrates how the soft core can be configured as a standard mass storage device, when connected directly to a PC.
In host mode, the board also demonstrates file transfers to a printer peripheral.
"Mentor Graphics has been actively involved in contributing to the On-The-Go specification and recognises the pivotal role that the standard will play in the future of portable device connectivity", said Dr Susheel Chandra, general manager, Mentor Graphics, Inventra Intellectual Property division.
"As the market leader in standards-based IP, Mentor Graphics is in lockstep with the standards bodies, and we are focused on delivering proven IP cores and reference solutions.
The availability of the new full-speed USB On-The-Go soft core, with an evaluation board, will save our customers considerable design time, effort and risk, allowing them to get new products quickly to market".
The Inventra MUSBFDRC is a synthesisable, dual-role USB controller macrocell that supports both host and peripheral functions in point-to-point data transfers.
Designers can now include a single core and configure as required by the application.
The device operates both as a function controller for a USB peripheral and as the host/peripheral in point-to-point communications with another USB function.
It supports session request and host negotiation protocols, and is configurable for up to 15 additional transmit endpoints and up to 15 additional receive endpoints.
It has a built-in PVCI-compatible CPU I/F, and an optional AMBA-AHB bridge with DMA controller.
A graphical user interface is provided for core configuration.
The Inventra MUSBFDRC core is designed to respect the power requirements of portable devices.
All Inventra USB cores are available in Verilog and VHDL, with full testbench and documentation.
USB device layer firmware is also available for designers of USB On-The-Go.
The Inventra MUSBFDRC soft IP core will be available early Q1 2002.
Boards will be available for demonstration and evaluation at the same time.
