简介：德州仪器（TI） 简化客户端电话设计 - C54x上实作eXpressDSP兼容算法

问：We would like to implement error correction and data compression algorithms as described in V.44 specification instead of ones described in V.42/V.42bis and implemented in CST. How can we do that in the most simple way?
答： Well, modem inside CST consists not only of data pump but it also has V.42 and V.42bis algorithms. And to unite them all, we have a special object called Modem Integrator. Modem Integrator, you can replace this object with another object and you can write

问：Could I get a custom CST chip that will contain only those algorithms that are necessary for my project?
答： At the moment, the way that we have set up this particular program is that we wanted to pull together a collection of the most widely used telephony software. So some of the voice-based-line telephony and data algorithms that are available in the market. A

问：SPIRIT公司提供的14种业界最流行的算法具体是什么样的算法?
答： These 14 algorithms are listed on the following website,

问：What"s the greatest advantage of eXpressDSP compare to others?
答： eXpressDSP integrates DSP development tools along with our third party. It will cut your time to have your products on market... Also, with the algorithm standard in the eXpressDSP, you could build you project in more robust structure.

问：建立一个基本的开发环境,需要多少投资?
我想个人建立一个开发环境,最少需要投入多少?
答： 需要一套xds510的DSP仿真器，与一套CCS for 54x，大概要几千元吧

问：设计的这客户端电话是否具有可视功能？
答： 没有

问：DSP同嵌入CPU相比的特点？
答： A good description is on our web. It shows you the advantage of DSP over microcontroller or General Purpose Processor.... Please go to the our DSP Village page, and click a link to "What is DSP?" on the left side of the page,

问：DSP为什么要初始化？
答： Usually, there are quite a few of onchip peripherals which need to be initialized before you could send/receive data to/from....

问：这一设计最大的优点在哪里？

答： C54CST chip is different to modem chipset mainly in the fact that it"s a programmable chip. With a regular modem chipset, you usually cannot write, add your own software inside the chipset. You have to put an external controller and another CPU or a h

问：这一简化设计对成本的影响有多大？

答： C54CST现在已经可以向TI公司订货，10K定量时，每片的价格为＄9.75
