Regulatory Compliance The Blackfin/SHARC USB EZ-Extender is designed to be used solely in a laboratory environment. The board is not intended for use as a consumer end product or as a portion of a consumer end product. The board is an open system design, which does not include a shielded enclosure and therefore may cause interference to other electrical devices in close prox-imity. This board should not be used in or near any medical equipment or RF devices.

The Blackfin/SHARC USB EZ-Extender is currently being processed for certification that it complies with the essential requirements of the Euro-pean EMC directive 89/336/EEC amended by 93/68/EEC and therefore carries the “CE” mark.

This evaluation system contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD precau-tions are recommended to avoid performance degradation or loss of func-tionality. Store unused boards in the protective shipping package.

PREFACE

Thank you for purchasing the Blackfin/SHARC USB EZ-Extender®,

Analog Devices, Inc. extender board to the EZ-Board™ evaluation system for the ADSP-BF518F, ADSP-BF526 Blackfin®, and ADSP-21469 SHARC® processors.

Blackfin processors are embedded processors that support a Media Instruction Set Computing (MISC) architecture. This architecture is the natural merging of RISC, media functions, and digital signal processing characteristics towards delivering signal processing performance in a microprocessor-like environment.

SHARC processors are based on a 32-bit super Harvard architecture that includes a unique memory architecture comprised of two large on-chip, dual-ported SRAM blocks coupled with a sophisticated IO processor, which gives a SHARC processor the bandwidth for sustained high-speed computations. SHARC processors represents today’s de facto standard for floating-point processing, targeted toward premium audio applications.

The EZ-Board and Blackfin/SHARC USB EZ-Extender are designed to be used in conjunction with the VisualDSP++® development environ-ment. VisualDSP++ offers a powerful programming tool with new flexibility that significantly decreases the time required to port software code to a processor, reducing time-to-market.

Product Overview

Product OverviewThe Blackfin/SHARC USB EZ-Extender is a separately sold extender board that plugs onto the expansion interface of the ADSP-BF518F, ADSP-BF526, and ADSP-21469 EZ-Board evaluation systems. The extender board aids the design and prototyping phases of the ADSP-BF518F, ADSP-BF526, and ADSP-21469 processor targeted applications.

The board extends the capabilities of the evaluation system by providing a connection between the asynchronous memory bus of the Black-fin/SHARC processor and a USB 2.0 device.

The following is a list of the Blackfin/SHARC USB EZ-Extender interfaces.

• USB 2.0 interface:

PLX Technology NET2272 device

USB driver and application code

• No power supply required: derives power from the EZ-Board

• CE certified

Before using any of the interfaces, follow the setup procedure in “Black-fin/SHARC USB EZ-Extender Setup” on page 1-2.

Example programs are available to demonstrate capabilities of the Black-fin/SHARC USB EZ-Extender board.

1 BLACKFIN/SHARC USB EZ-EXTENDER INTERFACES

This chapter provides the setup procedures for both the Blackfin/SHARC

USB EZ-Extender and EZ-Board (ADSP-BF518F, ADSP-BF526, or ADSP-21469) and describes the interfaces the extender supports.

The information is presented in the following order.

• “Blackfin/SHARC USB EZ-Extender Setup” on page 1-2

• “USB 2.0 Interface” on page 1-3

Blackfin/SHARC USB EZ-Extender Manual 1-1

Blackfin/SHARC USB EZ-Extender Setup

Blackfin/SHARC USB EZ-Extender SetupIt is very important to set up all components of the system containing the Blackfin/SHARC USB EZ-Extender, then apply power to the system. The following procedure is recommended for correct setup.

Power your system after these steps are completed:

1. Read the applicable design interface section in this chapter—the text provides an overview of the interface capabilities.

2. Read “System Architecture” on page 2-2 to understand physical connections of the extender board. For detailed information, refer to “Blackfin/SHARC USB EZ-Extender Schematic” on page B-1.

3. Set the jumpers on the Blackfin/SHARC USB EZ-Extender board. Use the block diagram in Figure 2-1 on page 2-2 in conjunction with “Jumper Settings” on page 2-3.

4. Set the switches and jumpers on the EZ-Board. If not already, familiarize yourself with the EZ-Board documentation and sche-matic drawings (see “Product Information”).

Compare the expansion interface signals of the Blackfin/SHARC USB EZ-Extender board with the EZ-Board signals to ensure there is no contention. For example, it may be necessary to disable other devices connected to the expansion interface of the processor and disable peripherals on the EZ-Board.

5. Install the Blackfin/SHARC USB EZ-Extender on the EZ-Board via the high speed expansion interface.

Blackfin/SHARC USB EZ-Extender Interfaces

USB SoftwareFor information about USB software, refer to the USB Software Readme.txt file located in the <install_path>\Blackfin\Examples\USB EZ-EXTENDER or <install_path>\214xx\Examples\USB EZ-EXTENDER VisualDSP++ directory.

USB 2.0 InterfaceThe Blackfin/SHARC USB EZ-Extender enables a connection between a USB 2.0 chip and Blackfin/SHARC processor without any other pro-grammable logic. The PLX Technology’s NET2272 controller ties directly to the asynchronous memory bus of the Blackfin or SHARC processor. You can read from and write to the USB 2.0 controller by addressing the named memory bank directly.

You can reset the NET2272 controller by asserting LOW one of the four GPIO signals of the expansion interface. Refer to the appropriate EZ-Board manual to learn how the GPIO signals connect to the processor.

The USB IRQ signal of the NET2272 controller connects to one of the four GPIO signals on the expansion interface. Refer to the appropriate EZ-Board document to learn how the GPIO signals connect to the processor.

The USB CS signal of the NET2272 controller connects to one of the four AMS signals on the expansion interface. Refer to the appropriate EZ-Board manual to learn how the AMS signals connect to the processor.

The jumper settings required for each of the respective EZ-Boards are described in the USB Software Readme.txt file located in the <install_path>\Blackfin\Examples\USB EZ-EXTENDER or
