2013-08-20

DM642評(píng)估模塊(EVM)是一種基于TMS320C642DSP的低成本高性能的視頻和影像開(kāi)發(fā)平臺(tái),旨在迅速實(shí)現(xiàn)多通道,多種格式數(shù)碼相機(jī)和其他面向未來(lái)應(yīng)用的應(yīng)用開(kāi)發(fā)套件。

基本特點(diǎn):

Tms320dm642是TI公司C6000系列DSP中最新的定點(diǎn)DSP,其核心是C6416型高性能數(shù)字信號(hào)處理器,具有極強(qiáng)的處理性能,高度的靈活性和可編程性,同時(shí)外圍集成了非常完整的音頻、視頻和網(wǎng)絡(luò)通信等設(shè)備及接口,特別適用于機(jī)器視覺(jué)、醫(yī)學(xué)成像、網(wǎng)絡(luò)視頻監(jiān)控、數(shù)字廣播以及基于數(shù)字視頻/圖像處理的消費(fèi)類(lèi)電子產(chǎn)品等高速DSP應(yīng)用領(lǐng)域。

方案特點(diǎn):

Developed in conjunction with Spectrum Digital, this PCI form factor EVM includes the necessary components to enable you to:
Start application software development immediately
Understand DSP functionality for video experts
