CS48L32-CNZ集成電路（IC）的DSP（數(shù)字信號(hào)處理器）規(guī)格書PDF中文資料

CS48L32-CNZ屬于集成電路（IC）的DSP（數(shù)字信號(hào)處理器）。由凌云邏輯制造生產(chǎn)的CS48L32-CNZDSP（數(shù)字信號(hào)處理器）數(shù)字信號(hào)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(duì)連續(xù)數(shù)據(jù)流連續(xù)執(zhí)行以乘法和加法運(yùn)算為主的算法，而不是以條件邏輯或大量并發(fā)進(jìn)程為主的算法。該器件通常用于諸如音頻或視頻信號(hào)處理等應(yīng)用。
