RISC-V overall progress

WordPress is so cumbersome (brut long text in SQL DB and other misconception (WTF?), buggy (especially to multilingual content missing) and hard to maintain on long term that I didn’t posted for long time I want to migrate. You can test the new log engine (here specialised in TIC-80 256 bytes code on https://256b.popolon.org/.

I continued my travel toward RISC-V I started as said in a previous post in may 2018.

RISC-V Benefits

Among the benefit of RISC-V beside other implementations:
* Open source and without license fee availability, allowing everyone to participate, implement and have full specifications
* Highest modularity for a processor in specifications, You can reduce the core to only the set of functions you want for a specific tasks, allowing less transistor/more compact specialized cores, and then multiply cores with some specialized in some kind of tasks.
* Vector extension

Tester un système Linux RISC-V avec qemu sur ARM et ArchLinuxARM

There is also an english tutorial with more informations here

Pour cela, on peut utiliser la distribution Busybear-linux, très limitée, mais déjà bien pour un premier test de Qemu avec RISC-V (Site officiel, le CPU à sources ouvertes et sous license libre). il a l’avantage de fournir un système pré-compilé, prêt à l’emploi ici : github.com/michaeljclark/busybear-linux/releases

Les deux fichiers indispensables sont :
* bbl.bz2 = boot
* busybear.bin.bz2 = système
