The ADSP-2191 is a 160 MIPS 16-bit fixed point DSP that is software compatible with DSPs in the ADSP-218x family, noted for its easy-to-use algebraic assembly syntax. Although the architectures are compatible, the ADSP-2191 architecture incorporates a number of enhancements that enables significant performance increases and improved C-compiler efficiency over its predecessor. The ADSP-2191 is available in a 144-lead LQFP and 144-ball mini-BGA package and is pin compatible with the low cost ADSP-2196 with 16K words RAM and 16K words ROM and the ADSP-2195 with 32K words RAM and 16K words ROM. Pin to pin-compatibility allows programmers a simple migration path to smaller memory models to reduce system cost without hardware redesign.
The ADSP-2191 is supported by a complete set of software and hardware development tools including VisualDSP++™, evaluation boards,and JTAG emulators.
The VisualDSP++ integrated development and debug environment (IDDE) features an efficient C/C++ compiler, statistical profiling, and the new VisualDSP® Kernel (VDK) - all designed to make software development faster.
ADI makes it easier to evaluate the ADSP-2191 for a specific application with the ADSP-2191 EZ-KIT Lite™ evaluation system. The EZ-KIT Lite includes an ADSP-2191 DSP evaluation board and evaluation suite with VisualDSP++.

Evaluation Kits (1)
EMULATOR-USB & HP USB ICE
Analog Devices’ cost-effective Universal Serial Bus (USB)-based emulator and High performance (HP) Universal Serial Bus (USB)-based emulator each provide an easy, portable, non-intrusive, target-based debugging solution for Analog Devices JTAG processors and DSPs. These powerful USB-based emulators perform a wide range of emulation functions, including single-step and full speed execution with pre-defined breakpoints, and viewing and/or altering of register and memory contents. With the ability to automatically detect and support multiple I/O voltages, the USB and HP USB emulators enable users to communicate with all of the Analog Devices JTAG processors and DSPs using either a full speed USB 1.1 or high speed USB 2.0 port on the host PC. Applications and data can easily and rapidly be tested and transferred between the emulators and the separately available VisualDSP++ development and debugging environment(sold separately).
The plug-and-play architecture of USB allows the emulators to be automatically detected and configured by the host operating system. It can also be connected to and disconnected from the host without opening the PC or turning off the power to the PC. A 3-meter cable is included to connect the emulators to the host PC, thus providing abundant accessibility to hard to reach targets.
The HP USB-based emulator also supports the Background
Telemetry Channel (BTC), a non-intrusive method
for exchanging data between the host and target
application without affecting the target system's
Part Number: ADZS-USB-ICE
