PREFACE
Thank you for purchasing the SHARC® USB EZ-Extender®, Analog
Devices, Inc. extension board to the EZ-KIT Lite® evaluation systems for
ADSP-21262, ADSP-21364, and ADSP-21369 processors.
The 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 processor targeted for premium audio
applications.
The EZ-KIT Lites and 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 time required to port software code to a processor,
reducing time-to-market.

1 USB EZ-EXTENDER
INTERFACE
This chapter provides the setup procedures for both the SHARC USB
EZ-Extender and EZ-KIT Lite (ADSP-21262, ADSP-21364, or
ADSP-21369) and describes the USB interface the extender supports.
USB EZ-Extender Setup
It is very important to set up all of the components of the system containing the USB EZ-Extender before applying power to that system. The
following procedure is recommended for the correct setup.
Power your system when these steps are completed:
1. Read the applicable design interface section in this chapter—the
text provides an overview of the capabilities of the interface.
2. Read “System Architecture” on page 2-1 to understand the physical
connections of the extension board. For detailed information, refer
to “USB EZ-Extender Schematic” on page B-1.
3. Remove any rubber feet that may be attached to the EZ-KIT Lite.
In place of these rubber feet, install the four nylon feet and screws
provided with the USB EZ-Extender. Install the nylon feet in the
mounting holes of the EZ-KIT Lite’s printed circuit board (PCB).
Flip the EZ-KIT Lite upside down so that the three expansion
headers (
SHARC USB EZ-Extender Manual 1-1
J1–3) are facing up.
USB 2.0 Interface
4. Set the jumper on the USB EZ-Extender board. Use the block diagram in Figure 2-1 on page 2-1 in conjunction with “Processor
Select Jumper (JP1)” on page 2-2.
5. Set the switches on the EZ-KIT Lite board. If not already, familiarize yourself with the documentation and schematics of the EZ-KIT
Lite (see “Related Documents”). Compare the expansion interface
signals of the USB EZ-Extender board with the signals of the
EZ-KIT Lite board 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 the push buttons on the
EZ-KIT Lite.
6. Install the USB EZ-Extender on the EZ-KIT Lite via the
three-connector expansion interface.
USB Software Documentation
For information on the USB software (host-side and device-side), refer to
the USB Software Readme.txt file located in the
…\212xx\Examples\USB EZ-EXTENDER or
…\213xx\Examples\USB EZ-EXTENDER subdirectory of the VisualDSP++
installation directory.
USB 2.0 Interface
The USB EZ-Extender allows you to connect a USB 2.0 chip to a SHARC
processor without any other programmable logic. PLX Technology’s
NetChip 2272 device ties directly to the parallel port or asynchronous
memory bank of the SHARC processor. You can read from and write to
the USB 2.0 controller by directly addressing the named memory bank.
1-2 SHARC USB EZ-Extender Manual
USB EZ-Extender Interface
You can reset the NetChip 2272 device by asserting
LOW these flag pins:
• FLAG2 on the ADSP-21262 and ADSP-21364 processors
• FLAG0 on the ADSP-21369 processor
The USB interrupt request pin (IRQ) line of the extender connects to
FLAG1 on the ADSP-21262, ADSP-21364, and ADSP-21369 processors.
This flag pin may be used for push buttons or LEDs on the respective
EZ-KIT Lites; consequently, the user must make the proper changes to
that EZ-KIT Lite.
When writing to and reading from the USB device using the EZ-KIT
Lites, use memory addresses listed in Table 1-1.

HARDWARE REFERENCE
This chapter describes the hardware design of the USB EZ-Extender. The
following topics are covered.
• “System Architecture” on page 2-1
Describes the extension board’s configuration.
• “Processor Select Jumper (JP1)” on page 2-2
Describes the configuration jumper’s functionality.
System Architecture
A block diagram of the SHARC USB EZ-Extender is shown in Figure 2-1.

Processor Select Jumper (JP1)
Processor Select Jumper (JP1)
Before using the SHARC USB EZ-Extender, follow the steps in “USB
EZ-Extender Setup” on page 1-1.
Figure 2-2 shows the location of the processor select jumper JP1. A
two-pin jumper can be placed on the respective jumper header for different functionality.
Figure 2-2. JP1 Jumper Settings
2-2 SHARC USB EZ-Extender Manual
USB EZ-Extender Hardware Reference
Table 2-1 describes the jumper settings and functionality. The jumper, by
default, must have no jumpers on any of its pins.
Table 2-1. JP1 Settings
EZ-KIT Lite JP1 Setting
ADSP-21262/ADSP-21364 No jumpers (default)
ADSP-21369 Installed
L
When using the extender with an ADSP-21262 or ADSP-21364
EZ-KIT Lite, you must not place any jumpers on JP1. Placing a
jumper on JP1 can damage the extender card and/or the EZ-KIT
Lite. When using the extender with an ADSP-21369 EZ-KIT Lite,
you must place the jumper on JP1.
