class="contentlabel" href="http://www.ex-cimer.com/news/listbylabel/label/DPU"><em>DPU</em></a>”</strong></p><p style="text-indent:28px">DPU是當(dāng)下算力基礎(chǔ)設(shè)施的核心創(chuàng)新之一，被寄予了數(shù)據(jù)中心三大支柱芯片之一的定位，戴上了“PU”的王冠。好比數(shù)據(jù)網(wǎng)絡(luò)的——高鐵時(shí)代，已經(jīng)不僅僅是連通城市問(wèn)題，而是徹底重構(gòu)了地理位置的邏輯距離。</p><p style="text-align:center"><img src="http://editerupload.eepw.com.cn/202406/1719300550550932.png" title="1719300550550932.png" alt="1719300550550932.png" width="500" height="333"/></p><p style="text-indent:28px">如果把CPU比做大腦、那么GPU就好比是肌肉、而DPU就是神經(jīng)中樞。CPU承載了應(yīng)用生態(tài)，決定了計(jì)算系統(tǒng)是否可以通用；GPU提供了高密度各類(lèi)精度的算力，決定了系統(tǒng)是否有足夠的“力量”；DPU負(fù)責(zé)數(shù)據(jù)在各種CPU和GPU之間高效流通，決定了系統(tǒng)是否能協(xié)同工作。</p><p style="text-indent:28px">關(guān)于DPU的重新定義，鄢貴海表示可以從兩個(gè)維度來(lái)深入理解。首先，DPU已超越單純的芯片范疇，它涵蓋了更廣泛的架構(gòu)和軟件生態(tài)。同時(shí)我們也強(qiáng)調(diào)了軟件護(hù)城的概念，這意味著基礎(chǔ)軟件和平臺(tái)在云端的深度集成與應(yīng)用是DPU技術(shù)落地的關(guān)鍵。因此，要真正發(fā)揮DPU的潛力，需要在架構(gòu)、軟件以及應(yīng)用這三個(gè)層次上共同發(fā)力。</p><p style="text-indent:28px">第二個(gè)維度涉及DPU的目標(biāo)應(yīng)用。傳統(tǒng)的DPU理解往往局限于卸載CPU上的某些任務(wù)，但這種觀(guān)念已經(jīng)過(guò)時(shí)且具有誤導(dǎo)性。如今的DPU應(yīng)用遠(yuǎn)不止于此，它處理的任務(wù)類(lèi)型更為廣泛和復(fù)雜。例如，在處理安全業(yè)務(wù)或構(gòu)建分布式安全機(jī)制時(shí)，DPU能夠輕松應(yīng)對(duì)CPU難以有效處理的負(fù)載。DPU已成為算網(wǎng)融合的關(guān)鍵組件，特別是在網(wǎng)絡(luò)中進(jìn)行計(jì)算的任務(wù)，這是CPU無(wú)法替代的。</p><p style="text-indent:28px">綜上所述，DPU的定義需要分層次理解，不能僅局限于芯片本身。同時(shí)，也應(yīng)該摒棄狹義的DPU功能認(rèn)知，而是將其置于更廣泛的分布式和集群性系統(tǒng)背景下考慮。這樣才能更準(zhǔn)確地把握DPU在計(jì)算機(jī)系統(tǒng)中所承載的負(fù)載類(lèi)型，從而更好地利用這一關(guān)鍵組件提升系統(tǒng)的整體性能。</p><p><strong>不同技術(shù)路線(xiàn)的DPU</strong></p><p> 全球DPU芯片市場(chǎng)正在經(jīng)歷一場(chǎng)由多家科技巨頭引領(lǐng)的變革。NVIDIA之外，Intel在2015年收購(gòu)Altera后，于2021年6月推出了IPU類(lèi)DPU產(chǎn)品，而Marvell自2018年起通過(guò)收購(gòu)Cavium、Avera

style="text-indent:28px">在技術(shù)層面，DPU的不同技術(shù)路徑各有優(yōu)劣。ASIC以其高性能、低功耗和低成本著稱(chēng)，但可編程性較低；FPGA提供了高靈活性和可編程性，但成本高昂、功耗較大；而基于SoC的技術(shù)路線(xiàn)，如NVIDIA的Blue Field DPU，以其可編程性和高靈活性成為DPU發(fā)展的主流方向，為更復(fù)雜、更廣泛的應(yīng)用場(chǎng)景提供了更優(yōu)的實(shí)施選項(xiàng)。</p><p style="text-indent:28px">中科馭數(shù)CTO盧文巖指出，F(xiàn)PGA在過(guò)去兩年中因其開(kāi)發(fā)效率而受到廣泛青睞，但其局限性也愈發(fā)明顯：功耗偏高、頻率難以大幅提升，且資源受限。因此，F(xiàn)PGA更適合作為DPU產(chǎn)品早期驗(yàn)證階段的產(chǎn)品路線(xiàn)。</p><p style="text-indent:28px">中科馭數(shù)所走的技術(shù)路線(xiàn)與AMD相近，強(qiáng)調(diào)可編程處理核心與輕量級(jí)控制的結(jié)合，這種技術(shù)策略近期表現(xiàn)出強(qiáng)勁的生命力。業(yè)界普遍認(rèn)可的重?cái)?shù)據(jù)通路加輕量級(jí)控制的趨勢(shì)，正是中科馭數(shù)與AMD所采納的發(fā)展方向，并經(jīng)過(guò)數(shù)年探索，這一路線(xiàn)已得到業(yè)界的廣泛認(rèn)同。</p><p><strong>打造獨(dú)立自主的DPU生態(tài)</strong></p><p
