Dup\u0103 ce compania Zilog a oprit produc\u021bia de procesoare 8-bit Z80 pe 15 aprilie, entuzia\u0219tii au ini\u021biat un proiect de creare a unui clon deschis al acestui procesor. Scopul proiectului este de a dezvolta un \u00eenlocuitor pentru procesoarele Z80, care s\u0103 fie interoperabil cu CPU-ul original Zilog Z80, compatibil cu acesta la nivel de conectivitate \u0219i capabil s\u0103 fie folosit \u00een computerul ZX Spectrum. Schemele, descrierile modulelor hardware \u00een limbajul Verilog \u0219i documenta\u021bia necesar\u0103 pentru produc\u021bie sunt distribuite sub licen\u021ba Apache 2.0. Produc\u021bia primei serii de procesoare FOSS Z80 este programat\u0103 pentru iunie 2024. <\/p>\n

\u00cen dezvoltarea cipului FOSS Z80 a fost folosit cadrul OpenROAD, dezvoltat pentru automatizarea procesului de proiectare a circuitelor integrate deschise, precum \u0219i instrumentarul Skywater PDK (Process Design Kit), care descrie procesul tehnologic de 130nm utilizat \u00een fabrica SkyWater \u0219i permite preg\u0103tirea fi\u0219ierelor de proiectare necesare pentru producerea circuitelor integrate. Pentru a reduce costurile de produc\u021bie a cipului pentru testare \u0219i proiectare, este folosit\u0103 infrastructura proiectului Tiny Tapeout. <\/p>\n

Rapid chip readiness is explained by the fact that instead of designing from scratch, the development used the previously evolving open project TV80 as a basis, providing a Verilog description of a CPU Z80-compatible core, distributed under the MIT license. After producing the first batch, the project developers plan to compare the chip with other implementations, such as A-Z80 \u2014 an FPGA-based implementation (Altera, Xilinx, and Lattice), distributed under the GPLv2 license, and Z80Explorer \u2014 a chip simulator that replicates the Zilog Z-80 at the electronic circuit level. <\/p>\n

Procesorul Z80 a fost lansat \u00een 1976 \u0219i a fost produs timp de 48 de ani. Cipul a c\u00e2\u0219tigat popularitate datorit\u0103 computerelor personale ZX Spectrum, consolelor de jocuri Sega \u0219i Game Boy, calculatoarelor Texas Instruments, precum \u0219i suportului \u00een sistemul de operare CP\/M. De asemenea, CPU Z80 a fost folosit activ \u00een echipamente industriale, diverse controlere, modeme, case de marcat, echipamente de m\u0103surare \u0219i dispozitive periferice.
