SuperSPARC vs UltraSPARC
SPARC (los ntawm Scalable Processor ARChitecture) yog RISC (Raws li Kev Qhia Qhia Teeb Meem) ISA (Instruction Set Architecture) tsim los ntawm Sun Microsystems. Cov SPARC microprocessors no tuaj yeem pom hauv phau ntawv sau rau supercomputers xws li kev lag luam servers. Lawv khiav cov kev khiav hauj lwm xws li Solaris, OpenBSD thiab NetBSD. SuperSPARC yog qhov version ntawm SPARC tsim nyob rau hauv 1992. SuperSPARC microprocessor siv SPARC V8 architecture version. UltraSPARC yog SPARC microprocessor, uas hloov SuperSPARC. UltraSPARC tau tsim nyob rau xyoo 1995 los ntawm Sun Microsystems. UltraSPARC siv V9 SPARC ISA thiab nws yog thawj SPARC microprocessor siv V9 ISA.
SuperSPARC
SuperSPARC yog tus qauv ntawm SPARC microprocessor uas tau tso tawm xyoo 1992 los ntawm Sun Microsystems. Nws yog codenamed Viking. SuperSPARC microprocessor siv SPARC V8 ISA. Sun qhia txog 33MHz thiab 40MHz SuperSPARC microprocessor versions. 3.1 lab transistors tau muaj nyob rau hauv SuperSPARC. Texas Instruments (TI) tsim cov microprocessor hauv Nyiv. SuperSPARC + thiab SuperSPARC-II yog ob lub ntsiab lus ntawm SuperSPARC. Lub hom phiaj tom qab tso SuperSPARC + microprocessor yog los kho ob peb kab nyob hauv thawj version. Txawm li cas los xij, SuperSPARC-II microprocessor, uas tau tso tawm xyoo 1994, yog qhov kev txhim kho zoo dua qub piv rau thawj SuperSAPRC microprocessor nrog ceev txog 80-90MHz. SuperSAPRC microprocessor muaj L1 cache ntawm 16KB. Nws L2 cache muaj peev xwm ntawm 2MB. L3 cache tsis nyob hauv SuperSPARC microprocessor. SuperSPARC-II tau codenamed Voyager.
UltraSPARC
UltraSPARC yog cov qauv ntawm SPARC microprocessor tso tawm los ntawm Sun Microsystems hauv xyoo 1995 hloov SuperSPARC-II. Nws siv V9 ISA ntawm SPARC architecture. Qhov tseeb, nws yog thawj SPARC microprocessor raws li 64 ntsis SPARC V9 ISA. Texas Instruments nqa tawm kev tsim ntawm 64 ntsis UltraSPARC. 32 64-ntsis nkag tau nyob rau hauv integer register file. Nws yog superscalar processor, uas ua tiav cov lus qhia hauv-kev txiav txim hauv cov raj xa dej nrog cuaj theem. Muaj ob chav ALU tab sis tsuas yog ib qho tuaj yeem ua haujlwm ntau thiab faib ua haujlwm. UltraSPARC microprocessor muaj ib hom tshwj xeeb ntawm floating point unit hu ua FGU (floating-point/graphics unit), uas muab kev txhawb nqa multimedia thiab. Muaj ob theem ntawm cache ua thawj thiab theem nrab. Thawj cache yog 16KB thiab theem nrab cache yog 512KB rau 4MB. Nws muaj rau lub tswv yim thiab tso zis ports nyob rau hauv daim ntawv ntawm peb nyeem thiab peb sau. Nws muaj 3.8 lab transistors.
Qhov txawv ntawm SuperSPARC thiab UltraSPARC yog dab tsi?
SuperSPARC thiab UltraSPARC microprocessors muaj ntau qhov sib txawv, tshwj xeeb tshaj yog txij li UltraSPARC microprocessor hloov SuperSPARC xyoo 1995. SuperSPARC microprocessor siv V8 SPARC ISA, thaum UltraSPARC microprocessor yog thawj SPARC microprocessor siv V9 SPARC ISA. Qhov tseeb, UltraSPARC microprocessor yog 64-ntsis microprocessor. To taub, UltraSPARC microprocessor muaj lub moos zaus ntau dua li SuperSPARC microprocessor. Nyob rau hauv cov nqe lus ntawm functional units, muaj ib tug ceeb sib txawv. Txhawm rau ua tiav lub moos ntau dua li SuperSPARC, UltraSPARC microprocessor muaj cov chav nyob yooj yim dua. Piv txwv li, qhov no tau ua tiav los ntawm kev tsis ua rau ALU units kom paub tseeb tias lub moos zaus tsis txwv. SuperSPARC microprocessor muaj 3.1 transistors, thaum UltraSPARC muaj 3.8 transistors. UltraSPARC microprocessor muaj qhov loj dua L2 cache piv rau SuperSPARC's L2. Zuag qhia tag nrho, UlatraSPARC muab kev ua tau zoo dua hauv txhua qhov chaw piv rau SuperSPARC.
