ADSP-2191M:  16-bit Fixed-Point DSP, 160 MIPS, 160K bytes RAM

Product Description

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 16 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.

Telephony Software Algorithms

For a complete solution, International Telecommunication Union (ITU) compliant high-quality speech codecs and robust echo cancellation software algorithms are available for the ADSP-2191 directly through ADI. This allows service providers to rapidly deploy high-quality, cost-effective and scalable next-generation voice convergent platforms.

ADI provides a selection of voice and tone detection algorithms that support the ADSP-2191 DSP. Algorithms such as: G.165, G.711, G.722, G.723, C.726, G.728, G.729, DTMF are some of many algorithms that can be easily integrated into your application.

Development Tools

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++.
