DI日前針對汽車、消費(fèi)級和專業(yè)級音響、多軸電機(jī)控制、能源分布系統(tǒng)等高性能應(yīng)用,推出了全新SHARC處理器ADSP-SC58x和ADSP-2158x系列,共計8款產(chǎn)品。R88M-WP1K530T-S1該系列采用兩個增強(qiáng)型SHARC+內(nèi)核和高級DSP加速器(FFT、FIR、IIR),105℃環(huán)境溫度下功耗不到2瓦,峰值性能超過每秒24千兆浮點運(yùn)算,據(jù)說可達(dá)前期SHARC產(chǎn)品的5倍以上,并超過最強(qiáng)勁競爭處理器達(dá)2倍以上。
ADI Processor- DSP亞洲區(qū)域經(jīng)理陸磊認(rèn)為,業(yè)界現(xiàn)在對DSP在性能、功耗、軟件IP保護(hù)和安全網(wǎng)絡(luò)連接、代碼管理等方面都提出了更為嚴(yán)苛的要求。“比如DSP的實時算法復(fù)雜程度現(xiàn)在就在不斷增加,傳統(tǒng)的定點算法也正逐漸向浮點算法過度。盡管實時性能有限,但很多廠商仍然集成了ARM內(nèi)核用于部分DSP信號處理任務(wù)。另一方面,行數(shù)更多的代碼、測試/系統(tǒng)集成、調(diào)試和滿足產(chǎn)品日程已經(jīng)成為客戶的首要挑戰(zhàn),R88M-WP1K530T-S1他們不僅需要任何功率水平的運(yùn)算性能和系統(tǒng)散熱性能,更需要原廠對產(chǎn)品可靠性和長期供貨做出承諾。
SHARC系列的新特性為了進(jìn)一步降低功耗,ADI這次在ADSP-SC58x系列中選用了兩顆450MHz SHARC+內(nèi)核,而不是直接將主頻拉升至900MHz。這樣做的目的,在于功耗與溫度不是線性而是指數(shù)關(guān)系,一顆900MHz內(nèi)核的功耗遠(yuǎn)遠(yuǎn)大于兩顆450MHz內(nèi)核,高溫下更是如此,很難實現(xiàn)全速運(yùn)行時系統(tǒng)功耗2W的目標(biāo)。在軟件IP保護(hù)日益成為工業(yè)安全領(lǐng)域的一個關(guān)切話題的情況下,新產(chǎn)品還提供了一個內(nèi)部的加密硬件加速器,可提供快速安全引導(dǎo)以及解密和認(rèn)證功能。
單芯片集成式SoC用于汽車音頻放大器
開源操作系統(tǒng)未來在工業(yè)領(lǐng)域更有前景
ADSP-SC58x/2158x受Crosscore Embedded Studio開發(fā)工具套件支持,為設(shè)計工程師提供了交互式實時開發(fā)工具,幫助其優(yōu)化設(shè)計、縮短上市時間。通過和Micrium合作,ADI在SHARC+和ARM Cortex-A5內(nèi)核上推出了μC/OSII andμC/OS-III實時核心,以及運(yùn)行于ARM Cortex-A5之上的Micrium USB主機(jī)、USB設(shè)備和文件系統(tǒng)堆棧。此外,ADI還提供了一款面向Cross Core Embedded Studio的Linux插件,R88M-WP1K530T-S1使客戶得以利用面向嵌入式Linux的通信堆棧和應(yīng)用包,使其運(yùn)行在ARM Cortex-A5內(nèi)核上。
