Porting socz80 (a retro microcomputer) to DE0-nano

UPDATE: Mikolas has added support for the DE2-70 board. Check his repo here: https://github.com/mikolas/socz80-de0_nano Due to my intrinsic, chronic curiosity, for a long time I wanted to get a in touch with FPGA and related technologies (Verilog, VHDL, etc…), and experience the feeling of total control, having both hardware and software subdued to my control (well, not so much, due to the mysterious and semi-secret process of synthetization and fitting done by the tools involved in the process, but you get the idea).

Enabling KVM virtualization on ARM (Allwinner A20)

Some time ago, ARM Holdings presented the new virtualization extensions for its processor architecture, which are now present on some models of the Cortex family, like the Cortex-A7 and Cortex-A15. Though it’s a quite recent technology, both KVM and Xen hypervisors already support such extensions, allowing to run virtualized Guests in the same way you can already do on x86. It’s true that current SoCs (System-on-Chip) and development boards doesn’t provide a number of cores and RAM memory that invite to run a significant number of Guests on them, but these are the first steps towards stabilization of ARM virtualization, paving the way for the future server-oriented ARM processors.
