ADSP-21992集成電路（IC）的DSP（數(shù)字信號處理器）規(guī)格書PDF中文資料

ADSP-21992屬于集成電路（IC）的DSP（數(shù)字信號處理器）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADSP-21992DSP（數(shù)字信號處理器）數(shù)字信號處理器是類似于微處理器或微控制器的器件，但區(qū)別在于其內(nèi)部架構(gòu)經(jīng)修改，適用于對連續(xù)數(shù)據(jù)流連續(xù)執(zhí)行以乘法和加法運算為主的算法，而不是以條件邏輯或大量并發(fā)進程為主的算法。該器件通常用于諸如音頻或視頻信號處理等應(yīng)用。

GENERAL DESCRIPTION

The ADSP-21992 is a mixed-signal DSP controller based on the ADSP-2199x DSP core, suitable for a variety of high performance industrial motor control and signal processing applications that require the combination of a high performance DSP and the mixed-signal integration of embedded control peripherals, such as analog-to-digital conversion with communications interfaces such as CAN. Target applications include industrial motor drives, uninterruptible power supplies, optical networking control, data acquisition systems, test and measurement Systems, and portable instrumentation.
