The Analog Devices ADZS-BFSHUSB-EZEXT 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 ADZS-BFSHUSB-EZEXT board extends the capabilities of the evaluation system by providing a connection between the asynchronous memory bus of the Blackfin/SHARC processor and a USB 2.0 device.
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.
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.
