Abstract

The Adaptive Vector Quantization (AVQ) device performs 4 to 1 compression and expansion of digitized voice data using the adaptive vector quantization algorithm. The device addresses off chip static RAM's to store and access the algorithm code book. Other than the RAM's and analog circuitry, the device is a one chip solution for both compression and decompression. The device was designed in a high level design language. It was then synthesized, simulated and laid out ala standard cell device. This talk will focus on the issues which came up during high level design I language synthesis, standard cell layout, and final timing verification.
Avq装置的设计与开发
自适应矢量量化(AVQ)设备使用自适应矢量量化算法对数字化语音数据进行4:1的压缩和扩展。该设备寻址片外静态RAM来存储和访问算法代码本。除了RAM和模拟电路之外,该设备是压缩和解压缩的单芯片解决方案。该装置是用高级设计语言设计的。然后将其合成、模拟并布置成一个标准的细胞装置。本讲座将重点讨论在高级设计阶段出现的问题,包括语言合成、标准单元布局和最终时序验证。
