ADSP-21584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-21584DSP（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(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處理等應(yīng)用。

GENERAL DESCRIPTION

The ADSP-SC58x/ADSP-2158x processors are members of the

SHARC? family of products. The ADSP-SC58x processor is

based on the SHARC+ dual core and the Arm? Cortex?-A5

core. The ADSP-SC58x/ADSP-2158x SHARC processors are

members of the SIMD SHARC family of digital signal processors

(DSPs) that feature Analog Devices, Inc., Super Harvard

Architecture?. These 32-bit/40-bit/64-bit floating-point processors

are optimized for high performance audio/floating-point

applications with large, on-chip, static random-access memory

(SRAM), multiple internal buses that eliminate input/output

(I/O) bottlenecks, and innovative digital audio interfaces (DAI).

New additions to the SHARC+ core include cache enhancements

and branch prediction, while maintaining instruction set

compatibility to previous SHARC products.

By integrating a set of industry leading system peripherals and

memory (see Table 1, Table 2, and Table 3), the Arm Cortex-A5

and SHARC processor is the platform of choice for applications

that require programmability similar to reduced instruction set

computing (RISC), multimedia support, and leading edge signal

processing in one integrated package. These applications span a

wide array of markets, including automotive, professional

audio, and industrial-based applications that require high floating-

point performance.
