L'objectif du projet est de d\u00e9velopper un remplacement des processeurs Z80 qui soit interchangeable avec le CPU Zilog Z80 original, compatible avec lui au niveau de la disposition des broches et pouvant \u00eatre utilis\u00e9 dans un ordinateur ZX Spectrum. Les sch\u00e9mas, descriptions des blocs mat\u00e9riels en Verilog et la documentation n\u00e9cessaire \u00e0 la production sont distribu\u00e9s sous la licence Apache 2.0. La production du premier lot d'\u00e9chantillons des processeurs FOSS Z80 est pr\u00e9vue pour juin 2024.     <\/p>\n<p>Dans le d\u00e9veloppement de la puce FOSS Z80, le framework OpenROAD est utilis\u00e9, d\u00e9velopp\u00e9 pour automatiser le processus de conception de circuits int\u00e9gr\u00e9s ouverts, ainsi que l'outil Skywater PDK (Process Design Kit), qui d\u00e9crit le processus de fabrication de 130 nm utilis\u00e9 \u00e0 l'usine SkyWater et permet de pr\u00e9parer les fichiers de conception n\u00e9cessaires \u00e0 la production de puces. Pour r\u00e9duire les co\u00fbts de production de la puce de test et de conception, l'infrastructure du projet Tiny Tapeout est utilis\u00e9e.     <\/p>\n<p>La rapidit\u00e9 de pr\u00e9paration de la puce s'explique par le fait que, au lieu de la concevoir de z\u00e9ro, son d\u00e9veloppement s'est appuy\u00e9 sur un projet ouvert pr\u00e9exist\u00e9, le TV80, qui fournit une description Verilog d'un c\u0153ur compatible avec le CPU Z80, distribu\u00e9 sous licence MIT. Apr\u00e8s la production du premier lot, les d\u00e9veloppeurs du projet envisagent de comparer la puce avec d'autres r\u00e9alisations, telles que l'A-Z80 \u2014 une impl\u00e9mentation bas\u00e9e sur FPGA (Altera, Xilinx et Lattice), fournie sous licence GPLv2, et le Z80Explorer \u2014 un simulateur de circuit int\u00e9gr\u00e9 qui reproduit le Zilog Z-80 au niveau des circuits \u00e9lectroniques.        <\/p>\n<p>Le processeur Z80 a \u00e9t\u00e9 introduit en 1976 et a \u00e9t\u00e9 produit pendant 48 ans. La puce est devenue c\u00e9l\u00e8bre gr\u00e2ce aux ordinateurs personnels ZX Spectrum, aux consoles de jeux Sega et Game Boy, aux calculatrices Texas Instruments, ainsi qu'\u00e0 son support dans le syst\u00e8me d'exploitation CP\/M. Parall\u00e8lement, le CPU Z80 a \u00e9galement \u00e9t\u00e9 largement utilis\u00e9 dans des \u00e9quipements industriels, divers contr\u00f4leurs, modems, caisses enregistreuses, \u00e9quipements de
