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 CrossCore® Embedded Studio (CCES) and VisualDSP++® software development environments. The development environment facilitates advanced application code development and debug, such as: • Create, compile, assemble, and link application programs written in C++, C, and SHARC USB EZ-Extender assembly • Load, run, step, halt, and set breakpoints in application programs • Read and write data and program memory • Read and write core and peripheral registers • Plot memory SHARC USB EZ-Extender Manual vii Product Overview To learn more about Analog Devices development software, go to http://www.analog.com/dsp/tools.

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 (J1–3) are facing up. SHARC USB EZ-Extender Manual 1-1 USB 2.0 Interface 4. Set the jumper on the USB EZ-Extender board. Use the block diagram in Figure 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 readme text files in the Examples folder of the 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. You can reset the NetChip 2272 device by asserting LOW these flag pins: 1-2 • FLAG2 on the ADSP-21262 and ADSP-21364 processors • FLAG0 on the ADSP-21369 processor SHARC USB EZ-Extender Manual USB EZ-Extender Interface 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. Table 1-1.

System Architecture A block diagram of the SHARC USB EZ-Extender is shown in Figure 2-1. Figure 2-1. Block Diagram SHARC USB EZ-Extender Manual 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.
