Kambani yeSiFive, yakavambwa nevagadziri veRISC-V yekuraira seti yekuvaka uye pane imwe nguva ichigadzira yekutanga prototype yeRISC-V-based processor, yakaunza itsva RISC-V CPU musimboti muSiFive Performance mutsara, iyo makumi mashanu. % nekukurumidza kupfuura yapfuura yepamusoro-yekupedzisira P50 musimboti uye iri pamusoro mukuita ARM Cortex-A550, yakanyanya simba processor yakavakirwa paArM architecture. MaSoCs akavakirwa pamusimboti mutsva anonangwa zvakanyanya kumasevha masisitimu uye nzvimbo dzekushandira, asi zvakare zvinogoneka kugadzira yakabviswa-pasi shanduro dzenharembozha uye dzakamisikidzwa michina.
Zvinonzi, zvichienzaniswa neP550, iyo itsva SiFive processor core ine 16 MB yeL3 cache pachinzvimbo che 4 MB, inogona kusanganisa anosvika gumi nematanhatu cores mune imwe chip pachinzvimbo che 16, inoshanda pa frequency inosvika 4 GHz pachinzvimbo che 3.5 GHz, inotsigira DDR2.4 memory uye PCI-Express 5 bhazi. Iyo yakajairwa dhizaini yemusimboti mutsva iri padyo neP5.0 uye zvakare iri modular muchisikigo, ichibvumira mamwe mabhuroki ane nyanzvi accelerators kana maGPU kuti awedzere kuSoC. Ruzivo rwakarongwa kuburitswa muna Zvita, uye FPGA-yakagadzirira RTL data ichaburitswa gore rinouya.
RISC-V inopa yakavhurika uye inochinjika yekuraira sisitimu yemuchina iyo inokutendera iwe kuti ugadzire yakavhurika SoCs uye mamicroprocessors ekushandisa zvisina tsarukano, pasina kuda mari kana kuisa mamiriro ekushandisa. Parizvino, zvichibva pane zvakatemwa zveRISC-V, 2.0 akasiyana emicroprocessor cores, 111 mapuratifomu, gumi nemaviri SoCs uye gumi nemaviri-akagadzirwa mabhodhi ari kuvandudzwa nemakambani akasiyana uye nharaunda pasi peakasiyana marezinesi emahara (BSD, MIT, Apache 31).
