ADSP-2191M:  16位定点DSP，160MIPS，40KB RAMADSP-2191M 功能框图

ADSP-2196是一款160 MIPS的16位定点DSP，与ADSP-218x系列DSP产品软件兼容，并以易于使用的代数汇编语法而闻名。虽然架构是兼容的，但相比前代产品，ADSP-2196架构包含了一些改进，使性能显著增强、C编译器效率有所提高。ADSP-2196采用144引脚LQFP封装和144焊球小型BGA封装，与内置64K字RAM的ADSP-2191和内置32K字RAM、16K字ROM的ADSP-2195引脚兼容。引脚兼容使程序员无需重新设计硬件就可简便地迁移到更小的存储器模型，以降低系统成本。

电话软件算法

为提供一个完整的解决方案，ADI公司可针对ADSP-2196直接提供符合国际电信联盟（ITU）标准的高品质的语音编解码器和鲁棒的回声消除软件算法。这使服务供应商能够快速部署高质量、具有成本效益并且可扩展的下一代语音汇聚平台。ADI公司提供了支持ADSP-2196 DSP的一系列语音和音调检测算法选择。许多算法如G.165、G.711、G.722、G.723、C.726、G.728、G.729、DTMF可以很容易地集成到您的应用程序中。

开发工具

一套完整的软件和硬件开发工具可支持ADSP-2196，包括VisualDSP++™、评估板和JTAG仿真器。VisualDSP++集成开发和调试环境（IDDE）具有高效的C/C++编译器、统计图表和新的VisualDSP® Kernel（VDK），所有特性都是设计用于加快软件开发速度。通过ADSP-2191 EZ-KIT Lite™评估系统，ADI公司使针对某种特定应用的ADSP-2196评估更加容易。EZ-KIT Lite包括一个让您下载、执行和调试ADSP-219x程序的监控程序。

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++.
