Proiectul Libre-SOC, care dezvolt\u0103 un cip deschis cu implementarea unei arhitecturi hibride \u00een stil CDC 6600, \u00een care instruc\u021biunile CPU, VPU \u0219i GPU nu sunt separate \u0219i sunt oferite \u00eentr-un singur ISA, a atins stadiul de transfer \u00een produc\u021bie a primului exemplar de test. Ini\u021bial, proiectul a fost dezvoltat sub numele de Libre RISC-V, dar a fost redenumit \u00een Libre-SOC dup\u0103 decizia de a \u00eenlocui RISC-V cu utilizarea arhitecturii setului de instruc\u021biuni (ISA) OpenPOWER 3.0. <\/p>\n

Proiectul are ca scop crearea unui sistem pe cip (SoC) complet func\u021bional, complet deschis \u0219i care nu necesit\u0103 pl\u0103\u021bi de licen\u021biere, care s\u0103 poat\u0103 fi utilizat \u00een computere cu un singur platan, netbook-uri \u0219i diverse dispozitive portabile. Pe l\u00e2ng\u0103 instruc\u021biunile \u0219i registrele generale ale CPU, Libre-SOC ofer\u0103 \u00eentr-un singur bloc func\u021bional al procesorului posibilit\u0103\u021bi pentru executarea de opera\u021bii vectoriale \u0219i calcule specializate, caracteristice VPU \u0219i GPU. Cipul utilizeaz\u0103 arhitectura setului de instruc\u021biuni OpenPOWER, extensia Simple-V cu instruc\u021biuni pentru vectorizare \u0219i procesarea paralel\u0103 a datelor, precum \u0219i instruc\u021biuni specializate pentru conversia \u00een ARGB \u0219i executarea opera\u021biunilor 3D tipice. <\/p>\n

Instruc\u021biunile GPU se concentreaz\u0103 pe utilizarea cu API-ul grafic Vulkan, iar VPU pe accelerarea conversiei YUV-RGB \u0219i decodificarea formatelor MPEG1\/2, MPEG4 ASP (xvid), H.264, H.265, VP8, VP9, AV1, MP3, AC3, Vorbis \u0219i Opus. Pentru Mesa se dezvolt\u0103 un driver liber, care utilizeaz\u0103 capacit\u0103\u021bile Libre-SOC pentru a oferi o implementare software accelerat\u0103 hardware a API-ului grafic Vulkan. De exemplu, shader-urile Vulkan pot fi translatate cu ajutorul unui motor JIT pentru a fi executate folosind instruc\u021biuni specializate disponibile \u00een Libre-SOC. <\/p>\n

\u00cen urm\u0103torul prototip de test se pl\u0103nuie\u0219te implementarea extensiei SVP64 (Vectorizare variabil\u0103), permi\u021b\u00e2nd utilizarea Libre-SOC ca procesor vectorial (pe l\u00e2ng\u0103 32 de registre de 64 de bi\u021bi de uz general, vor fi furnizate 128 de registre pentru calcule vectoriale). Primul prototip include doar un nucleu care lucreaz\u0103 la o frecven\u021b\u0103 de 300 Mhz, dar \u00een decurs de doi ani se preconizeaz\u0103 lansarea unei versiuni cu 4 nuclee, apoi cu 8 nuclee, iar pe termen lung, o variant\u0103 cu 64 de nuclee. <\/p>\n

Prima lot de cipuri va fi fabricat de compania TSMC utiliz\u00e2nd tehnologia de proces de 180nm. Toate realiz\u0103rile proiectului sunt distribuite sub licen\u021be libere, inclusiv fi\u0219ierele \u00een format GDS-II care descriu \u00eentreaga topologie a cipului, suficiente pentru a \u00eencepe propria produc\u021bie. Libre-SOC va fi primul cip complet independent bazat pe arhitectura Power, fabricat nu de compania IBM. \u00cen dezvoltare a fost folosit limbajul de descriere a hardware-ului nMigen (HDL bazat pe Python, f\u0103r\u0103 utilizarea VHDL \u0219i Verilog), bibliotecile de celule standard FlexLib de la proiectul Chips4Makers \u0219i uneltele VLSI libere Coriolis2 pentru conversia din HDL \u00een GDS-II. <\/p>\n

Dezvoltarea Libre-SOC a fost finan\u021bat\u0103 de funda\u021bia NLnet, care a alocat 400.000 de euro pentru crearea unui chip complet deschis \u00een cadrul programului de dezvoltare a solu\u021biilor tehnice fundamentale verificate \u0219i de \u00eencredere. Chipul are dimensiunea de 5,5×5,9 mm \u0219i include 130.000 de por\u021bi logice. Acesta con\u021bine patru module SRAM de 4KB \u0219i un bloc de ajustare automat\u0103 a frecven\u021bei (PLL) de 300 MHz.
