DI日前針對汽車、消費(fèi)級(jí)和專業(yè)級(jí)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(jì)8款產(chǎn)品。R88M-WP1K530T-S1該系列采用兩個(gè)增強(qiáng)型SHARC+內(nèi)核和高級(jí)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(diǎn)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(shí)時(shí)算法復(fù)雜程度現(xiàn)在就在不斷增加，傳統(tǒng)的定點(diǎn)算法也正逐漸向浮點(diǎn)算法過度。盡管實(shí)時(shí)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(hào)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(shí)現(xiàn)全速運(yùn)行時(shí)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(gè)關(guān)切話題的情況下，新產(chǎn)品還提供了一個(gè)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(jì)工程師提供了交互式實(shí)時(shí)開發(fā)工具，幫助其優(yōu)化設(shè)計(jì)、縮短上市時(shí)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(shí)時(shí)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。
