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 proximity. 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 European 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 precautions are recommended to avoid performance degradation or loss of functionality. Store unused boards in the protective shipping package.

Blackfin/SHARC USB EZ-Extender Manual
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 environment. 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.

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
Blackfin/SHARC USB EZ-Extender Setup
It 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 schematic 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.

USB 2.0 Interface
The Blackfin/SHARC USB EZ-Extender enables a connection between a
USB 2.0 chip and Blackfin/SHARC processor without any other programmable 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
\Blackfin\Examples\USB EZ-EXTENDER or
Blackfin/SHARC USB EZ-Extender Manual

Jumper Settings
USB Chip Select Jumper (JP1)
The USB chip select jumper (JP1) connects an AMS signal from the
EZ-Board to the chip select input on the NET2272 controller. The AMS0–
3 signals are available. By default, the jumper is installed on pins 7 and 8,
which connect AMS3 to the chip select signal.
USB IRQ Jumper (JP2)
The USB IRQ jumper (JP2) connects a general-purpose IO signal from
the EZ-Board to the interrupt output on the NET2272 controller. The
GPIO1–4 signals are available. By default, the jumper is installed on pins 1
and 2, which connect GPIO1 to the interrupt signal.
USB Soft Reset Jumper (JP3)
The soft reset jumper (JP3) connects a general-purpose signal from the
EZ-Board to the reset input on the NET2272 controller. GPIO1–4 are
available. By default, the jumper is installed on pins 7 and 8, which connect GPIO4 to the reset signal.
