ADSP-21469KBCZ-4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-21469KBCZ-4DSP（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-21467/ADSP-21469 SHARC? processors are members of the SIMD SHARC family of DSPs that feature Analog Devices’ Super Harvard Architecture. The processors are source code compatible with the ADSP-2126x, ADSP-2136x, ADSP-2137x, and ADSP-2116x DSPs, as well as with first generation ADSP-2106x SHARC processors in SISD (singleinstruction, single-data) mode. These 32-bit/40-bit floatingpoint processors are optimized for high performance audio applications with their large on-chip SRAM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications/peripheral interfaces (DAI/DPI).
