詞語解釋
CPCI(CompactPCI)是一種通用的嵌入式系統(tǒng)架構(gòu),它提供了一種高性能、可靠、可擴(kuò)展的解決方案,可以用于各種通信應(yīng)用。 CPCI是一種通用的嵌入式架構(gòu),它使用一種名為“CompactPCI”的插槽,可以容納各種各樣的模塊,包括CPU、存儲(chǔ)器、I/O、網(wǎng)絡(luò)接口和其他嵌入式模塊。CPCI架構(gòu)的優(yōu)勢(shì)在于它提供了一種靈活的解決方案,可以根據(jù)應(yīng)用需求添加和更換模塊,以滿足不同的應(yīng)用需求。 CPCI架構(gòu)可以用于各種通信應(yīng)用,例如,它可以用于建立網(wǎng)絡(luò)、實(shí)現(xiàn)數(shù)據(jù)傳輸、實(shí)現(xiàn)安全通信等。它可以將多個(gè)模塊連接在一起,使系統(tǒng)更加穩(wěn)定可靠。此外,CPCI架構(gòu)還可以用于實(shí)現(xiàn)虛擬化,以支持多種應(yīng)用程序的運(yùn)行。 總之,CPCI是一種通用的嵌入式系統(tǒng)架構(gòu),它可以用于各種通信應(yīng)用,例如建立網(wǎng)絡(luò)、實(shí)現(xiàn)數(shù)據(jù)傳輸、實(shí)現(xiàn)安全通信等,并可以根據(jù)應(yīng)用需求添加和更換模塊,以滿足不同的應(yīng)用需求。 一、CPCI簡介 Compact PCI(Compact Peripheral Component Interconnect)簡稱CPCI,中文又稱緊湊型PCI,是國際工業(yè)計(jì)算機(jī)制造者聯(lián)合會(huì)(PCI Industrial Computer Manufacturer's Group,簡稱PICMG)于1994提出來的一種總線接口標(biāo)準(zhǔn)。是以PCI電氣規(guī)范為標(biāo)準(zhǔn)的高性能工業(yè)用總線。CPCI的CPU及外設(shè)同標(biāo)準(zhǔn)PCI是相同的,并且CPCI系統(tǒng)使用與傳統(tǒng)PCI系統(tǒng)相同的芯片、防火墻和相關(guān)軟件。從根本上說,它們是一致的,因此操作系統(tǒng)、驅(qū)動(dòng)和應(yīng)用程序都感覺不到兩者的區(qū)別,將一個(gè)標(biāo)準(zhǔn)PCI插卡轉(zhuǎn)化成CPCI插卡幾乎不需重新設(shè)計(jì),只要物理上重新分配一下即可。為了將PCI SIG的PCI總線規(guī)范用在工業(yè)控制計(jì)算機(jī)系統(tǒng),1995年11月PCI工業(yè)計(jì)算機(jī)制造者聯(lián)合會(huì)(PICMIG)頒布了CPCI規(guī)范1.0版,以后相繼推出了PCI-PCI Bridge規(guī)范、Computer Telephony TDM規(guī)范和User-defined I/O pin assignment規(guī)范。簡言之CPCI總線 = PCI總線的電氣規(guī)范 + 標(biāo)準(zhǔn)針孔連接器(IEC-1076-4-101) + 歐洲卡規(guī)范(IEC297/IEEE 1011.1)。 CPCI的出現(xiàn)不僅讓諸如CPU、硬盤等許多原先基于PC的技術(shù)和成熟產(chǎn)品能夠延續(xù)應(yīng)用,也由于在接口等地方做了重大改進(jìn),使得采用CPCI技術(shù)的服務(wù)器、工控電腦等擁有了高可靠性、高密度的優(yōu)點(diǎn)。CPCI是基于PCI電氣規(guī)范開發(fā)的高性能工業(yè)總線,適用于3U和6U高度的電路插板設(shè)計(jì)。CPCI電路插板從前方插入機(jī)柜,I/O數(shù)據(jù)的出口可以是前面板上的接口或者機(jī)柜的背板。它的出現(xiàn)解決了多年來電信系統(tǒng)工程師與設(shè)備制造商面臨的棘手問題,比如傳統(tǒng)電信設(shè)備總線VME(Versa Module Euro card)與工業(yè)標(biāo)準(zhǔn)PCI(Peripheral Component Interconnect)總線不兼容問題。 二、CPCI的特點(diǎn) CPCI技術(shù)是在PCI技術(shù)基礎(chǔ)之上經(jīng)過改造而成,具體有三個(gè)方面: 一是繼續(xù)采用PCI局部總線技術(shù); 二是拋棄IPC傳統(tǒng)機(jī)械結(jié)構(gòu),改用經(jīng)過20年實(shí)踐檢驗(yàn)了的高可靠歐洲卡結(jié)構(gòu),改善了散熱條件、提高了抗振動(dòng)沖擊能力、符合電磁兼容性要求; 三是拋棄IPC的金手指式互連方式,改用2mm密度的針孔連接器,具有氣密性、防腐性,進(jìn)一步提高了可靠性,并增加了負(fù)載能力。 CPCI所具有可熱插拔(Hot Swap)、高開放性、高可靠性、。CPCI技術(shù)中最突出、最具吸引力的特點(diǎn)是熱插拔(Hot Swap)。簡言之,就是在運(yùn)行系統(tǒng)沒有斷電的條件下,拔出或插入功能模板,而不破壞系統(tǒng)的正常工作的一種技術(shù)。熱插拔一直是電信應(yīng)用的要求,也為每一個(gè)工業(yè)自動(dòng)化系統(tǒng)所渴求。它的實(shí)現(xiàn)是:在結(jié)構(gòu)上采用三種不同長度的引腳插針,使得模板插入或拔出時(shí),電源和接地、PCI總線信號(hào)、熱插拔啟動(dòng)信號(hào)按序進(jìn)行;采用總線隔離裝置和電源的軟啟動(dòng);在軟件上,操作系統(tǒng)要具有即插即用功能。目前CPCI總線熱插拔技術(shù)正在從基本熱切換技術(shù)向高可用性方向發(fā)展。 CPCI標(biāo)準(zhǔn)具有種種優(yōu)點(diǎn)。它與傳統(tǒng)的桌面PCI系統(tǒng)完全兼容,在64位/66M總線接口下能提供每秒高達(dá)512MB的帶寬。它支持用在桌面PC和工作站上的完全一樣的接口芯片。使用CPCI能利用在桌面工作站上開發(fā)的整個(gè)應(yīng)用,無需任何改變就能將其移到目標(biāo)環(huán)境,極大地提高了產(chǎn)品推向市場(chǎng)的時(shí)間。利用CPCI技術(shù)使得電信設(shè)備OEM能利用與桌面應(yīng)用系統(tǒng)同樣的先進(jìn)技術(shù),同時(shí)還具有針對(duì)桌面系統(tǒng)設(shè)計(jì)的大量PCI芯片所帶來的規(guī)模經(jīng)濟(jì)和低成本特性。其產(chǎn)品成本上往往低于同等功能的VME產(chǎn)品,僅略高于通常的工控機(jī)IPC(IPC,Industrial Personal Computer)產(chǎn)品。 CPCI規(guī)范自制定以來,已歷經(jīng)多個(gè)版本。最新的PICMG 3.0所規(guī)范的CPCI技術(shù)架構(gòu)在一個(gè)更加開放、標(biāo)準(zhǔn)的平臺(tái)上,有利于各類系統(tǒng)集成商、設(shè)備供應(yīng)商提供更加便捷快速的增值服務(wù),為用戶提供更高性價(jià)比的產(chǎn)品和解決方案。PICMG 3.0標(biāo)準(zhǔn)是一個(gè)全新的技術(shù),與PICMG 2.x完全不同,特別在速度上與PICMG 2.x相比,PICMG 3.0速度每秒可達(dá)2Tb。PICMG 3.0主要將應(yīng)用在高帶寬電信傳輸上,以適應(yīng)未來電信的發(fā)展,PICMG 2.x則仍是目前CPCI的主流,并將在很長時(shí)間內(nèi)主宰CPCI的應(yīng)用。 三、CPCI的應(yīng)用 CPCI所具有高開放性、高可靠性、可熱插拔(Hot Swap),使該技術(shù)除了可以廣泛應(yīng)用在通訊、網(wǎng)絡(luò)、計(jì)算機(jī)電話整和(Computer Telephony),也適合實(shí)時(shí)系統(tǒng)控制(Real Time Machine Control)、產(chǎn)業(yè)自動(dòng)化、實(shí)時(shí)數(shù)據(jù)采集(Real-Time Data Acquisition)、軍事系統(tǒng)等需要高速運(yùn)算、智能交通、航空航天、醫(yī)療器械、水利等模塊化及高可靠度、可長期使用的應(yīng)用領(lǐng)域。由于CPCI擁有較高的帶寬,它也適用于一些高速數(shù)據(jù)通信的應(yīng)用,包括服務(wù)器、路由器、交換機(jī)等。 管腳定義 Pin Name Des cription Z1 GND Ground Z2 GND Ground Z3 GND Ground Z4 GND Ground Z5 GND Ground Z6 GND Ground Z7 GND Ground Z8 GND Ground Z9 GND Ground Z10 GND Ground Z11 GND Ground Z12 KEY Keyed (no pin) Z13 KEY Keyed (no pin) Z14 KEY Keyed (no pin) Z15 GND Ground Z16 GND Ground Z17 GND Ground Z18 GND Ground Z19 GND Ground Z20 GND Ground Z21 GND Ground Z22 GND Ground Z23 GND Ground Z24 GND Ground Z25 GND Ground Z26 GND Ground Z27 GND Ground Z28 GND Ground Z29 GND Ground Z30 GND Ground Z31 GND Ground Z32 GND Ground Z33 GND Ground Z34 GND Ground Z35 GND Ground Z36 GND Ground Z37 GND Ground Z38 GND Ground Z39 GND Ground Z40 GND Ground Z41 GND Ground Z42 GND Ground Z43 GND Ground Z44 GND Ground Z45 GND Ground Z46 GND Ground Z47 GND Ground A1 5V +5 VDC A2 TCK Test Clock A3 INTA# Interrupt A A4 BRSV Bused Reserved (don't use) A5 BRSV Bused Reserved (don't use) A6 REQ# Request PCI transfer A7 AD(30) Address/Data 30 A8 AD(26) Address/Data 26 A9 C/BE(3)# Command: Byte Enable A10 AD(21) Address/Data 21 A11 AD(18) Address/Data 18 A12 KEY Keyed (no pin) A13 KEY Keyed (no pin) A14 KEY Keyed (no pin) A15 3.3V +3.3 VDC A16 DEVSEL# Device Select A17 3.3V +3.3 VDC A18 SERR# System Error A19 3.3V +3.3 VDC A20 AD(12) Address/Data 12 A21 3.3V +3.3 VDC A22 AD(7) Address/Data 7) A23 3.3V +3.3 VDC A24 AD(1) Address/Data 1) A25 5V +5 VDC A26 CLK1 Clock ??

一、CPCI簡介 Compact PCI(Compact Peripheral Component Interconnect)簡稱CPCI,中文又稱緊湊型PCI,是國際工業(yè)計(jì)算機(jī)制造者聯(lián)合會(huì)(PCI Industrial Computer Manufacturer's Group,簡稱PICMG)于1994提出來的一種總線接口標(biāo)準(zhǔn)。是以PCI電氣規(guī)范為標(biāo)準(zhǔn)的高性能工業(yè)用總線。CPCI的CPU及外設(shè)同標(biāo)準(zhǔn)PCI是相同的,并且CPCI系統(tǒng)使用與傳統(tǒng)PCI系統(tǒng)相同的芯片、防火墻和相關(guān)軟件。從根本上說,它們是一致的,因此操作系統(tǒng)、驅(qū)動(dòng)和應(yīng)用程序都感覺不到兩者的區(qū)別,將一個(gè)標(biāo)準(zhǔn)PCI插卡轉(zhuǎn)化成CPCI插卡幾乎不需重新設(shè)計(jì),只要物理上重新分配一下即可。為了將PCI SIG的PCI總線規(guī)范用在工業(yè)控制計(jì)算機(jī)系統(tǒng),1995年11月PCI工業(yè)計(jì)算機(jī)制造者聯(lián)合會(huì)(PICMIG)頒布了CPCI規(guī)范1.0版,以后相繼推出了PCI-PCI Bridge規(guī)范、Computer Telephony TDM規(guī)范和User-defined I/O pin assignment規(guī)范。簡言之CPCI總線 = PCI總線的電氣規(guī)范 + 標(biāo)準(zhǔn)針孔連接器(IEC-1076-4-101) + 歐洲卡規(guī)范(IEC297/IEEE 1011.1)。 CPCI的出現(xiàn)不僅讓諸如CPU、硬盤等許多原先基于PC的技術(shù)和成熟產(chǎn)品能夠延續(xù)應(yīng)用,也由于在接口等地方做了重大改進(jìn),使得采用CPCI技術(shù)的服務(wù)器、工控電腦等擁有了高可靠性、高密度的優(yōu)點(diǎn)。CPCI是基于PCI電氣規(guī)范開發(fā)的高性能工業(yè)總線,適用于3U和6U高度的電路插板設(shè)計(jì)。CPCI電路插板從前方插入機(jī)柜,I/O數(shù)據(jù)的出口可以是前面板上的接口或者機(jī)柜的背板。它的出現(xiàn)解決了多年來電信系統(tǒng)工程師與設(shè)備制造商面臨的棘手問題,比如傳統(tǒng)電信設(shè)備總線VME(Versa Module Euro card)與工業(yè)標(biāo)準(zhǔn)PCI(Peripheral Component Interconnect)總線不兼容問題。 二、CPCI的特點(diǎn) CPCI技術(shù)是在PCI技術(shù)基礎(chǔ)之上經(jīng)過改造而成,具體有三個(gè)方面: 一是繼續(xù)采用PCI局部總線技術(shù); 二是拋棄IPC傳統(tǒng)機(jī)械結(jié)構(gòu),改用經(jīng)過20年實(shí)踐檢驗(yàn)了的高可靠歐洲卡結(jié)構(gòu),改善了散熱條件、提高了抗振動(dòng)沖擊能力、符合電磁兼容性要求; 三是拋棄IPC的金手指式互連方式,改用2mm密度的針孔連接器,具有氣密性、防腐性,進(jìn)一步提高了可靠性,并增加了負(fù)載能力。 CPCI所具有可熱插拔(Hot Swap)、高開放性、高可靠性、。CPCI技術(shù)中最突出、最具吸引力的特點(diǎn)是熱插拔(Hot Swap)。簡言之,就是在運(yùn)行系統(tǒng)沒有斷電的條件下,拔出或插入功能模板,而不破壞系統(tǒng)的正常工作的一種技術(shù)。熱插拔一直是電信應(yīng)用的要求,也為每一個(gè)工業(yè)自動(dòng)化系統(tǒng)所渴求。它的實(shí)現(xiàn)是:在結(jié)構(gòu)上采用三種不同長度的引腳插針,使得模板插入或拔出時(shí),電源和接地、PCI總線信號(hào)、熱插拔啟動(dòng)信號(hào)按序進(jìn)行;采用總線隔離裝置和電源的軟啟動(dòng);在軟件上,操作系統(tǒng)要具有即插即用功能。目前CPCI總線熱插拔技術(shù)正在從基本熱切換技術(shù)向高可用性方向發(fā)展。 CPCI標(biāo)準(zhǔn)具有種種優(yōu)點(diǎn)。它與傳統(tǒng)的桌面PCI系統(tǒng)完全兼容,在64位/66M總線接口下能提供每秒高達(dá)512MB的帶寬。它支持用在桌面PC和工作站上的完全一樣的接口芯片。使用CPCI能利用在桌面工作站上開發(fā)的整個(gè)應(yīng)用,無需任何改變就能將其移到目標(biāo)環(huán)境,極大地提高了產(chǎn)品推向市場(chǎng)的時(shí)間。利用CPCI技術(shù)使得電信設(shè)備OEM能利用與桌面應(yīng)用系統(tǒng)同樣的先進(jìn)技術(shù),同時(shí)還具有針對(duì)桌面系統(tǒng)設(shè)計(jì)的大量PCI芯片所帶來的規(guī)模經(jīng)濟(jì)和低成本特性。其產(chǎn)品成本上往往低于同等功能的VME產(chǎn)品,僅略高于通常的工控機(jī)IPC(IPC,Industrial Personal Computer)產(chǎn)品。 CPCI規(guī)范自制定以來,已歷經(jīng)多個(gè)版本。最新的PICMG 3.0所規(guī)范的CPCI技術(shù)架構(gòu)在一個(gè)更加開放、標(biāo)準(zhǔn)的平臺(tái)上,有利于各類系統(tǒng)集成商、設(shè)備供應(yīng)商提供更加便捷快速的增值服務(wù),為用戶提供更高性價(jià)比的產(chǎn)品和解決方案。PICMG 3.0標(biāo)準(zhǔn)是一個(gè)全新的技術(shù),與PICMG 2.x完全不同,特別在速度上與PICMG 2.x相比,PICMG 3.0速度每秒可達(dá)2Tb。PICMG 3.0主要將應(yīng)用在高帶寬電信傳輸上,以適應(yīng)未來電信的發(fā)展,PICMG 2.x則仍是目前CPCI的主流,并將在很長時(shí)間內(nèi)主宰CPCI的應(yīng)用。 三、CPCI的應(yīng)用 CPCI所具有高開放性、高可靠性、可熱插拔(Hot Swap),使該技術(shù)除了可以廣泛應(yīng)用在通訊、網(wǎng)絡(luò)、計(jì)算機(jī)電話整和(Computer Telephony),也適合實(shí)時(shí)系統(tǒng)控制(Real Time Machine Control)、產(chǎn)業(yè)自動(dòng)化、實(shí)時(shí)數(shù)據(jù)采集(Real-Time Data Acquisition)、軍事系統(tǒng)等需要高速運(yùn)算、智能交通、航空航天、醫(yī)療器械、水利等模塊化及高可靠度、可長期使用的應(yīng)用領(lǐng)域。由于CPCI擁有較高的帶寬,它也適用于一些高速數(shù)據(jù)通信的應(yīng)用,包括服務(wù)器、路由器、交換機(jī)等。 管腳定義 Pin Name Des cription Z1 GND Ground Z2 GND Ground Z3 GND Ground Z4 GND Ground Z5 GND Ground Z6 GND Ground Z7 GND Ground Z8 GND Ground Z9 GND Ground Z10 GND Ground Z11 GND Ground Z12 KEY Keyed (no pin) Z13 KEY Keyed (no pin) Z14 KEY Keyed (no pin) Z15 GND Ground Z16 GND Ground Z17 GND Ground Z18 GND Ground Z19 GND Ground Z20 GND Ground Z21 GND Ground Z22 GND Ground Z23 GND Ground Z24 GND Ground Z25 GND Ground Z26 GND Ground Z27 GND Ground Z28 GND Ground Z29 GND Ground Z30 GND Ground Z31 GND Ground Z32 GND Ground Z33 GND Ground Z34 GND Ground Z35 GND Ground Z36 GND Ground Z37 GND Ground Z38 GND Ground Z39 GND Ground Z40 GND Ground Z41 GND Ground Z42 GND Ground Z43 GND Ground Z44 GND Ground Z45 GND Ground Z46 GND Ground Z47 GND Ground A1 5V +5 VDC A2 TCK Test Clock A3 INTA# Interrupt A A4 BRSV Bused Reserved (don't use) A5 BRSV Bused Reserved (don't use) A6 REQ# Request PCI transfer A7 AD(30) Address/Data 30 A8 AD(26) Address/Data 26 A9 C/BE(3)# Command: Byte Enable A10 AD(21) Address/Data 21 A11 AD(18) Address/Data 18 A12 KEY Keyed (no pin) A13 KEY Keyed (no pin) A14 KEY Keyed (no pin) A15 3.3V +3.3 VDC A16 DEVSEL# Device Select A17 3.3V +3.3 VDC A18 SERR# System Error A19 3.3V +3.3 VDC A20 AD(12) Address/Data 12 A21 3.3V +3.3 VDC A22 AD(7) Address/Data 7) A23 3.3V +3.3 VDC A24 AD(1) Address/Data 1) A25 5V +5 VDC A26 CLK1 Clock ??
