Product Details

The ADSP-2196 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-2196 architecture incorporates a number of enhancements that enables significant performance increases and improved C-compiler efficiency over its predecessor. The ADSP-2196 is available in a 144-lead LQFP package and is pin compatible with the ADSP-2191 with 64K words RAM 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-2196 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-2196 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-2196 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-2196 for a specific application with the ADSP-219x EZ-KIT Lite evaluation system. The EZ-KIT Lite includes a monitor program that lets you download, execute and debug ADSP-219x programs.
