Khampani ea SiFive, e thehiloeng ke baetsi ba moralo oa litaelo tsa RISC-V 'me ka nako e' ngoe e ntse e lokisa prototype ea pele ea processor e thehiloeng ho RISC-V, e hlahisitse motheo o mocha oa RISC-V CPU moleng oa SiFive Performance, e leng 50. % e potlakile ho feta ea mantlha e fetileng ea P550 mme e phahametse ts'ebetso ea ARM Cortex-A78, processor e matla ka ho fetesisa e ipapisitseng le meralo ea ARM. Li-SoCs tse ipapisitseng le motheo o mocha li lebisitsoe haholo ho litsamaiso tsa li-server le li-workstations, empa hape hoa khoneha ho theha mefuta e theohileng bakeng sa lisebelisoa tsa mehala le tse kentsoeng.
Ho boleloa hore, ha ho bapisoa le P550, SiFive processor core e ncha e na le 16 MB ea L3 cache sebakeng sa 4 MB, e ka kopanya ho fihla ho li-cores tse 16 ho chip e le 'ngoe ho e-na le 4, e sebetsa ka makhetlo a ho fihlela ho 3.5 GHz sebakeng sa 2.4 GHz, e tšehetsa memori ea DDR5 le bese ea PCI-Express 5.0. Meaho e akaretsang ea mantlha e ncha e haufi le P550 hape e na le sebopeho sa modular, e lumellang li-block tse ling tse nang le li-accelerator tse khethehileng kapa li-GPU hore li ekeletsoe ho SoC. Lintlha li reriloe ho phatlalatsoa ka Tšitoe, 'me lintlha tsa RTL tse lokiselitsoeng ke FPGA li tla phatlalatsoa selemong se tlang.
RISC-V e fana ka sistimi ea litaelo ea mochini e bulehileng le e tenyetsehang e u lumellang hore u thehe li-SoC le li-microprocessor tse bulehileng ka botlalo bakeng sa lits'ebetso tse qotsitsoeng, ntle le ho hloka meputso kapa ho beha maemo a ts'ebeliso. Hajoale, ho ipapisitsoe le litlhaloso tsa RISC-V, mefuta e 2.0 ea li-microprocessor cores, li-platform tse 111, li-SoCs tse 31 le liboto tse seng li entsoe tse 12 li ntse li ntlafatsoa ke lik'hamphani le sechaba se fapaneng tlasa lilaesense tse fapaneng tsa mahala (BSD, MIT, Apache 12).
